    Parameters:
    
    texture - which texture unit to make active. One of: TEXTURE0 GL_TEXTURE[1-31]
  - glAttachShader
```
public void glAttachShader(int program,
                           int shader)
```
    Description copied from interface: GL
    
    Reference Page
    
    Attaches a shader object to a program object.
    In order to create a complete shader program, there must be a way to specify the list of things that will be linked together. Program objects provide this mechanism. Shaders that are to be linked together in a program object must first be attached to that program object. glAttachShader attaches the shader object specified by shader to the program object specified by program. This indicates that shader will be included in link operations that will be performed on program.
    
    All operations that can be performed on a shader object are valid whether or not the shader object is attached to a program object. It is permissible to attach a shader object to a program object before source code has been loaded into the shader object or before the shader object has been compiled. It is permissible to attach multiple shader objects of the same type because each may contain a portion of the complete shader. It is also permissible to attach a shader object to more than one program object. If a shader object is deleted while it is attached to a program object, it will be flagged for deletion, and deletion will not occur until glDetachShader is called to detach it from all program objects to which it is attached.
    
    Specified by:
    
    glAttachShader in interface GL
    
    Parameters:
    
    program - the program object to which a shader object will be attached.
    
    shader - the shader object that is to be attached.
  - glBeginQuery

    Creates a query object and makes it active.
    
    Specified by:
    
    glBeginQuery in interface GL
    
    Parameters:
    
    target - the target type of query object established.
    
    query - the name of a query object.
  - glBindBuffer
```

```
    Description copied from interface: GL
    
    Reference Page
    
    Binds a named buffer object.
    
    Specified by:
    
    glBindBuffer in interface GL
    
    Parameters:
    
    target - the target to which the buffer object is bound.
    
    buffer - the name of a buffer object.
  - glBindTexture
```
public void glBindTexture(int target,
                          int texture)
```
    Description copied from interface: GL
    
    Reference Page
    
    Binds the a texture to a texture target.
    While a texture object is bound, GL operations on the target to which it is bound affect the bound object, and queries of the target to which it is bound return state from the bound object. If texture mapping of the dimensionality of the target to which a texture object is bound is enabled, the state of the bound texture object directs the texturing operation.
    
    Specified by:
    
    glBindTexture in interface GL
    
    Parameters:
    
    target - the texture target.
    
    texture - the texture object to bind.
  - glBlendFunc

public void glBufferData(int target,
                         java.nio.FloatBuffer data,
                         int usage)
```
    Description copied from interface: GL
    Reference Page
    
    Creates and initializes a buffer object's data store.
    usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage), and second, the nature of that access. The frequency of access may be one of these:
    - STREAM - The data store contents will be modified once and used at most a few times.
    - STATIC - The data store contents will be modified once and used many times.
    - DYNAMIC - The data store contents will be modified repeatedly and used many times.
    The nature of access may be one of these:

    Creates and initializes a buffer object's data store.
    usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage), and second, the nature of that access. The frequency of access may be one of these:
    - STREAM - The data store contents will be modified once and used at most a few times.
    - STATIC - The data store contents will be modified once and used many times.
    - DYNAMIC - The data store contents will be modified repeatedly and used many times.
    The nature of access may be one of these:
    - DRAW - The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.
    - READ - The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.

    Deletes texture objects. After a texture object is deleted, it has no contents or dimensionality, and its name is again unused. If a texture that is currently bound to any of the target bindings of BindTexture is deleted, it is as though BindTexture had been executed with the same target and texture zero. Additionally, special care must be taken when deleting a texture if any of the images of the texture are attached to a framebuffer object.

    Constructs a sequence of geometric primitives by successively transferring elements for count vertices. Elements first through first + count – 1 of each enabled non-instanced array are transferred to the GL.
    If an array corresponding to an attribute required by a vertex shader is not enabled, then the corresponding element is taken from the current attribute state. If an array is enabled, the corresponding current vertex attribute value is unaffected by the execution of this function.
    
    Specified by:
    
    glDrawArrays in interface GL
    
    Parameters:
    
    mode - the kind of primitives being constructed.
    
    first - the first vertex to transfer to the GL.
    
    count - the number of vertices after first to transfer to the GL.

```
    Description copied from interface: GL
    Reference Page
    
    Implementations denote recommended maximum amounts of vertex and index data, which may be queried by calling glGet with argument MAX_ELEMENTS_VERTICES and MAX_ELEMENTS_INDICES. If end - start + 1 is greater than the value of GL_MAX_ELEMENTS_VERTICES, or if count is greater than the value of GL_MAX_ELEMENTS_INDICES, then the call may operate at reduced performance. There is no requirement that all vertices in the range start end be referenced. However, the implementation may partially process unused vertices, reducing performance from what could be achieved with an optimal index set.
    
    When glDrawRangeElements is called, it uses count sequential elements from an enabled array, starting at start to construct a sequence of geometric primitives. mode specifies what kind of primitives are constructed, and how the array elements construct these primitives. If more than one array is enabled, each is used.
    
    Vertex attributes that are modified by glDrawRangeElements have an unspecified value after glDrawRangeElements returns. Attributes that aren't modified maintain their previous values.
    Errors
    It is an error for indices to lie outside the range start end, but implementations may not check for this situation. Such indices cause implementation-dependent behavior.
    - GL_INVALID_ENUM is generated if mode is not an accepted value.
    - GL_INVALID_VALUE is generated if count is negative.
    - GL_INVALID_VALUE is generated if end < start.
    - GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input primitive type of the geometry shader in the currently installed program object.
    - GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object's data store is currently mapped.
    Specified by:
    
    glDrawRangeElements in interface GL
    
    Parameters:
    
    mode - the kind of primitives to render.

    Description copied from interface: GL
    
    Reference Page
    Returns the current boolean value of the specified state variable.
    LWJGL note: The state that corresponds to the state variable may be a single value or an array of values. In the case of an array of values, LWJGL will not validate if params has enough space to store that array. Doing so would introduce significant overhead, as the OpenGL state variables are too many. It is the user's responsibility to avoid JVM crashes by ensuring enough space for the returned values.
    
    Specified by:

  - glGetError
```
public int glGetError()
```
    Description copied from interface: GL
    
    Reference Page
    Returns error information. Each detectable error is assigned a numeric code. When an error is detected, a flag is set and the code is recorded. Further errors, if they occur, do not affect this recorded code. When GetError is called, the code is returned and the flag is cleared, so that a further error will again record its code. If a call to GetError returns NO_ERROR, then there has been no detectable error since the last call to GetError (or since the GL was initialized).
    
    Specified by:
    
    glGetError in interface GL

    The depth values of all fragments generated by the rasterization of a polygon may be offset by a single value that is computed for that polygon. This function determines that value.
    factor scales the maximum depth slope of the polygon, and units scales an implementation-dependent constant that relates to the usable resolution of the depth buffer. The resulting values are summed to produce the polygon offset value.
    
    Specified by:

    Description copied from interface: GL
    
    Reference Page
    
    ReadPixels obtains values from the selected read buffer from each pixel with lower left hand corner at (x + i, y + j) for 0 <= i < width and 0 <= j < height; this pixel is said to be the i^th pixel in the j^th row. If any of these pixels lies outside of the window allocated to the current GL context, or outside of the image attached to the currently bound read framebuffer object, then the values obtained for those pixels are undefined. When READ_FRAMEBUFFER_BINDING is zero, values are also undefined for individual pixels that are not owned by the current context. Otherwise, ReadPixels obtains values from the selected buffer, regardless of how those values were placed there.
    
    Specified by:
    
    glReadPixels in interface GL
    
    Parameters:
    
    x - the left pixel coordinate

    Reference Page
    
    Defines the scissor rectangle for all viewports. The scissor test is enabled or disabled for all viewports using Enable or Disable with the symbolic constant SCISSOR_TEST. When disabled, it is as if the scissor test always passes. When enabled, if left <= x_w < left + width and bottom <= y_w < bottom + height for the scissor rectangle, then the scissor test passes. Otherwise, the test fails and the fragment is discarded.
    
    Specified by:
    
    glScissor in interface GL
    
    Parameters:
    
    x - the left scissor rectangle coordinate.

    Description copied from interface: GL
    
    Reference Page
    
    Sets the source code in shader to the source code in the array of strings specified by strings. Any source code previously stored in the shader object is completely replaced. The number of strings in the array is specified by count. If length is NULL, each string is assumed to be null terminated. If length is a value other than NULL, it points to an array containing a string length for each of the corresponding elements of strings. Each element in the length array may contain the length of the corresponding string (the null character is not counted as part of the string length) or a value less than 0 to indicate that the string is null terminated. The source code strings are not scanned or parsed at this time; they are simply copied into the specified shader object.
    
    Specified by:
    
    glShaderSource in interface GL
    
    Parameters:
    
    shader - the shader object whose source code is to be replaced,
    
    string - an array of pointers to strings containing the source code to be loaded into the shader
    
    length - storage for the string lengths, or null for null-terminated strings

```
    Description copied from interface: GLExt
    Reference Page
    Creates and initializes a buffer object's data store.
    usage is a hint to the GL implementation as to how a buffer object's data store will be accessed. This enables the GL implementation to make more intelligent decisions that may significantly impact buffer object performance. It does not, however, constrain the actual usage of the data store. usage can be broken down into two parts: first, the frequency of access (modification and usage), and second, the nature of that access. The frequency of access may be one of these:
    - STREAM - The data store contents will be modified once and used at most a few times.
    - STATIC - The data store contents will be modified once and used many times.
    - DYNAMIC - The data store contents will be modified repeatedly and used many times.
    The nature of access may be one of these:
    - DRAW - The data store contents are modified by the application, and used as the source for GL drawing and image specification commands.
    - READ - The data store contents are modified by reading data from the GL, and used to return that data when queried by the application.
    - COPY - The data store contents are modified by reading data from the GL, and used as the source for GL drawing and image specification commands.
    Specified by:
    
    glBufferData in interface GLExt
    
    Parameters:
    
    target - the target buffer object.
    
    data - a pointer to data that will be copied into the data store for initialization, or NULL if no data is to be copied.
    
    usage - the expected usage pattern of the data store.

    Description copied from interface: GL
    
    Reference Page
    
    ReadPixels obtains values from the selected read buffer from each pixel with lower left hand corner at (x + i, y + j) for 0 <= i < width and 0 <= j < height; this pixel is said to be the i^th pixel in the j^th row. If any of these pixels lies outside of the window allocated to the current GL context, or outside of the image attached to the currently bound read framebuffer object, then the values obtained for those pixels are undefined. When READ_FRAMEBUFFER_BINDING is zero, values are also undefined for individual pixels that are not owned by the current context. Otherwise, ReadPixels obtains values from the selected buffer, regardless of how those values were placed there.
    
    Specified by:
    
    glReadPixels in interface GL
    
    Parameters:
    
    x - the left pixel coordinate
    
    y - the lower pixel coordinate
    
    width - the number of pixels to read in the x-dimension
    
    height - the number of pixels to read in the y-dimension
    
    format - the pixel format.
    
    type - the pixel type.
    
    offset - a buffer in which to place the returned pixel data/

```
    Description copied from interface: GLExt
    
    Causes the client to block and wait for a sync object to become signaled. If sync is signaled when glClientWaitSync is called, glClientWaitSync returns immediately, otherwise it will block and wait for up to timeout nanoseconds for sync to become signaled.

```
    Description copied from interface: GL2
    
    Reference Page - This function is deprecated and unavailable in the Core profile
    The alpha test discards a fragment conditionally based on the outcome of a comparison between the incoming fragment’s alpha value and a constant value. The comparison is enabled or disabled with the generic Enable and Disable commands using the symbolic constant ALPHA_TEST. When disabled, it is as if the comparison always passes. The test is controlled with this method.
    
    Specified by:
    
    glAlphaFunc in interface GL2
    
    Parameters:
    
    func - a symbolic constant indicating the alpha test function. One of: NEVER ALWAYS LESS LEQUAL EQUAL GEQUAL GREATER NOTEQUAL
    
    ref - a reference value clamped to the range [0, 1]. When performing the alpha test, the GL will convert the reference value to the same representation as the fragment's alpha value (floating-point or fixed-point).

  - glPolygonMode
```
public void glPolygonMode(int face,
                          int mode)
```
    Description copied from interface: GL2
    
    Reference Page
    Controls the interpretation of polygons for rasterization.
    FILL is the default mode of polygon rasterization. Note that these modes affect only the final rasterization of polygons: in particular, a polygon's vertices are lit, and the polygon is clipped and possibly culled before these modes are applied. Polygon antialiasing applies only to the FILL state of PolygonMode. For POINT or LINE, point antialiasing or line segment antialiasing, respectively, apply.
    
    Specified by:
    
    glPolygonMode in interface GL2
    
    Parameters:
    
    face - the face for which to set the rasterizing method. One of: FRONT BACK FRONT_AND_BACK
    
    mode - the rasterization mode. One of: POINT LINE FILL
