  - glActiveTexture
```
void glActiveTexture(int texture)
```
    Reference Page
    
    Selects which texture unit subsequent texture state calls will affect. The number of texture units an implementation supports is implementation dependent.
    
    Parameters:
    
    texture - which texture unit to make active. One of:
    TEXTURE0 GL_TEXTURE[1-31]
  - glAttachShader
```
void glAttachShader(int program,
                    int shader)
```
    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.
    
    Parameters:
    
    program - the program object to which a shader object will be attached.
    
    shader - the shader object that is to be attached.
  - glBeginQuery
```
void glBeginQuery(int target,
                  int query)
```
    Reference Page
    
    Creates a query object and makes it active.
    
    Parameters:
    
    target - the target type of query object established.
    
    query - the name of a query object.
  - glBindBuffer
```
void glBindBuffer(int target,
                  int buffer)
```
    Reference Page
    
    Binds a named buffer object.
    
    Parameters:
    
    target - the target to which the buffer object is bound.
    
    buffer - the name of a buffer object.
  - glBindTexture
```
void glBindTexture(int target,
                   int texture)
```
    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.
    
    Parameters:
    
    target - the texture target.
    
    texture - the texture object to bind.
  - glBlendEquationSeparate

                         int dfactorAlpha)
```
    Reference Page
    
    Specifies pixel arithmetic for RGB and alpha components separately.
    
    Parameters:
    
    sfactorRGB - how the red, green, and blue blending factors are computed. The initial value is GL_ONE.
    
    dfactorRGB - how the red, green, and blue destination blending factors are computed. The initial value is GL_ZERO.

  - glBufferData
```
void glBufferData(int target,

                  int usage)
```
    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.
    Parameters:
    
    target - the target buffer object.
    
    dataSize - the size in bytes of the buffer object's new data store
    
    usage - the expected usage pattern of the data store.

  - glDeleteTextures
```
void glDeleteTextures(java.nio.IntBuffer textures)
```
    Reference Page
    
    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.
    
    Unused names in textures that have been marked as used for the purposes of GenTextures are marked as unused again. Unused names in textures are silently ignored, as is the name zero.
    
    Parameters:
    
    textures - contains n names of texture objects to be deleted.

```
void glDrawArrays(int mode,
                  int first,
                  int count)
```
    Reference Page
    
    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.
    
    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.
  - glDrawRangeElements
```
void glDrawRangeElements(int mode,
                         int start,
                         int end,
                         int count,
                         int type,
                         long indices)
```
    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.
    Parameters:
    
    mode - the kind of primitives to render.
    
    start - the minimum array index contained in indices.
    
    end - the maximum array index contained in indices.
    
    count - the number of elements to be rendered.
    
    type - the type of the values in indices.
    
    indices - a pointer to the location where the indices are stored.

```
    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.
    
    Parameters:
    
    pname - the state variable.
    
    params - a scalar or buffer in which to place the returned data.

    Reference Page
    
    Returns a subset of a buffer object's data store.
    
    Parameters:

    data - a pointer to the location where buffer object data is returned.
  - glGetError
```
int glGetError()
```
    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).

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.
    
    Parameters:
    
    shader - the shader object whose source code is to be replaced,
    
    strings - an array of pointers to strings containing the source code to be loaded into the shader
