NAMEglTexBuffer, glTextureBuffer − attach a buffer object's data store to a buffer texture object
C SPECIFICATIONvoid glTexBuffer(GLenum target, GLenum internalformat, GLuint buffer); void glTextureBuffer(GLuint texture, GLenum internalformat, GLuint buffer);
PARAMETERStarget Specifies 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​.
DESCRIPTIONglTexBuffer 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 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 Sized Internal Format Base Type Components Norm 0 none;'>none;'> 1 2 3 GL_R8 ubyte 1 YES R 0 0 1 GL_R16 ushort 1 YES R 0 0 1 GL_R16F half 1 NO R 0 0 1 GL_R32F float 1 NO R 0 0 1 GL_R8I byte 1 NO R 0 0 1 GL_R16I short 1 NO R 0 0 1 GL_R32I int 1 NO R 0 0 1 GL_R8UI ubyte 1 NO R 0 0 1 GL_R16UI ushort 1 NO R 0 0 1 GL_R32UI uint 1 NO R 0 0 1 GL_RG8 ubyte 2 YES R G 0 1 GL_RG16 ushort 2 YES R G 0 1 GL_RG16F half 2 NO R G 0 1 GL_RG32F float 2 NO R G 0 1 GL_RG8I byte 2 NO R G 0 1 GL_RG16I short 2 NO R G 0 1 GL_RG32I int 2 NO R G 0 1 GL_RG8UI ubyte 2 NO R G 0 1 GL_RG16UI ushort 2 NO R G 0 1 GL_RG32UI uint 2 NO R G 0 1 GL_RGB32F float 3 NO R G B 1 GL_RGB32I int 3 NO R G B 1 GL_RGB32UI uint 3 NO R G B 1 GL_RGBA8 uint 4 YES R G B A GL_RGBA16 short 4 YES R G B A GL_RGBA16F half 4 NO R G B A GL_RGBA32F float 4 NO R G B A GL_RGBA8I byte 4 NO R G B A GL_RGBA16I short 4 NO R G B A GL_RGBA32I int 4 NO R G B A GL_RGBA8UI ubyte 4 NO R G B A GL_RGBA16UI ushort 4 NO R G B A GL_RGBA32UI uint 4 NO R G B A When a buffer object is attached to a buffer texture, the buffer object's data store is taken as the texture's texel array​. The number of texels in the buffer texture's texel array is given by $$ \left\lfloor { size \over { components \times sizeof(base\_type) } } \right\rfloor $$ where $size$ is the size of the buffer object in basic machine units (the value of GL_BUFFER_SIZE for buffer), and $components$ and $base\_type$ are the element count and base data type for elements, as specified in the table above​. The number of texels in the texel array is then clamped to the value of the implementation−dependent limit GL_MAX_TEXTURE_BUFFER_SIZE​. When a buffer texture is accessed in a shader, the results of a texel fetch are undefined if the specified texel coordinate is negative, or greater than or equal to the clamped number of texels in the texel array​.
ERRORSGL_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​.
