 Null texel fetch function.
static void fetch_null_texelf (const struct gl_texture_image *texImage, GLint i, GLint j, GLint k, GLfloat *texel)

 Return datatype and number of components per texel for the given gl_texture_format.

Variables

Default GLchan-based formats
Notes about the predefined gl_texture_formats:

1. There are 1D, 2D and 3D functions for fetching texels from texture images, returning both GLchan values and GLfloat values. (six functions in total) You don't have to provide both the GLchan and GLfloat functions; just one or the other is OK. Mesa will use an "adaptor" to convert between GLchan/GLfloat when needed. Since the adaptors have small performance penalty, we provide both GLchan and GLfloat functions for some common formats like RGB, RGBA.

Function Documentation

struct gl_texture_format* _mesa_choose_tex_format ( GLcontext *  ctx,
GLint  internalFormat,
GLenum  format,
GLenum  type 
) [read]

Choose an appropriate texture format given the format, type and internalFormat parameters passed to glTexImage().

Parameters:
ctx the GL context.
internalFormat user's prefered internal texture format.
format incoming image pixel format.
type incoming image data type.
Returns:
a pointer to a gl_texture_format object which describes the choosen texture format, or NULL on failure.
This is called via dd_function_table::ChooseTextureFormat. Hardware drivers will typically override this function with a specialized version.

void _mesa_format_to_type_and_comps ( const struct gl_texture_format *  format,
GLenum *  datatype,
GLuint *  comps 
)

Return datatype and number of components per texel for the given gl_texture_format.

static void fetch_null_texel ( const struct gl_texture_image *  texImage,
GLint  i,
GLint  j,
GLint  k,
GLchan *  texel 
) [static]

Null texel fetch function.

Have to have this so the FetchTexel function pointer is never NULL.

static void fetch_null_texelf ( const struct gl_texture_image *  texImage,
GLint  i,
GLint  j,
GLint  k,
