NAME¶
glTexBuffer, glTextureBuffer - attach a buffer object's data store to a buffer texture objectC SPECIFICATION¶
void glTexBuffer(GLenum target,
GLenum internalFormat,
GLuint buffer);
void glTextureBuffer(GLuint texture,
GLenum internalformat,
GLuint buffer);
PARAMETERS¶
targetSpecifies the target to which the texture is bound for
glTexBuffer. Must be GL_TEXTURE_BUFFER.
texture
Specifies the texture object name for
glTextureBuffer.
internalFormat
Specifies the internal format of the data in the store
belonging to buffer.
buffer
Specifies the name of the buffer object whose storage to
attach to the active buffer texture.
DESCRIPTION¶
glTexBuffer and glTextureBuffer attaches the data store of a specified buffer object to a specified texture object, and specify the storage format for the texture image found found in the buffer object. The texture object must be a buffer texture. If buffer is zero, any buffer object attached to the buffer texture is detached and no new buffer object is attached. If buffer is non-zero, it must be the name of an existing buffer object. internalformat specifies the storage format, and must be one of the following sized internal formats: internalformat specifies the storage format, and must be one of the following sized internal formats:Component | |||||||

ERRORS¶
GL_INVALID_ENUM is generated by glTexBuffer if target is not GL_TEXTURE_BUFFER. GL_INVALID_OPERATION is generated by glTextureBuffer if texture is not the name of an existing texture object. GL_INVALID_ENUM is generated by glTextureBuffer if the effective target of texture is not GL_TEXTURE_BUFFER. GL_INVALID_ENUM is generated if internalformat is not one of the sized internal formats described above. GL_INVALID_OPERATION is generated if buffer is not zero and is not the name of an existing buffer object.ASSOCIATED GETS¶
