- 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
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 interfaceGL
- Parameters:
program
- the program object to which a shader object will be attached.shader
- the shader object that is to be attached.
-
glBeginQuery
public void glBeginQuery(int target, int query) Description copied from interface:GL
Creates a query object and makes it active.
- Specified by:

in interfaceGL
- Parameters:
target
- the target type of query object established.query
- the name of a query object.
-
glBindBuffer
public void glBindBuffer(int target, int buffer) Description copied from interface:GL
Binds a named buffer object.
- Specified by:
glBindBuffer
in interfaceGL
- 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
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 interfaceGL
- Parameters:
target
- the texture target.texture
- the texture object to bind.
-
glBlendFunc

glBufferData
Description copied from interface:GL
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.

vertices. Elementsfirst
throughfirst + 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.

Implementations denote recommended maximum amounts of vertex and index data, which may be queried by calling glGet with argument
MAX_ELEMENTS_VERTICES
andMAX_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.
ErrorsIt 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:

glBufferData
Description copied from interface:GLExt
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 interfaceGLExt
- Parameters:
target
- the target buffer object.data
- a pointer to data that will be copied into the data store for initialization, orNULL
