g3d_texture_load_cached ()

G3DImage *
g3d_texture_load_cached (G3DContext *context,
                         G3DModel *model,
                         const gchar *filename);

Loads a texture image from file and attaches it to a hash table in the model. On a second try to load this texture it is returned from cache.

g3d_texture_load_from_stream ()

G3DImage *
g3d_texture_load_from_stream (G3DContext *context,
                              G3DModel *model,
                              G3DStream *stream);

Load a texture image from a stream. The file type is determined by the extension of the stream URI, so it should be valid. If model is not NULL the texture image is cached (or retrieved from cache if available).

g3d_texture_load ()

G3DImage *
g3d_texture_load (G3DContext *context,
                  const gchar *filename);

Load a texture from a file. The type of file is determined by the file extension.

g3d_texture_free ()

void
g3d_texture_free (G3DImage *texture);

Frees all memory used by this texture image.

g3d_texture_prepare ()

gboolean
g3d_texture_prepare (G3DImage *texture);

Resizes the image to dimensions which are a power of 2 to be usable as an OpenGL texture. (FIXME: unimplemented)

g3d_texture_flip_y ()

gboolean
g3d_texture_flip_y (G3DImage *texture);

Mirror the image along the x axis - all y coordinates are inverted.

g3d_texture_merge_alpha ()

G3DImage *
g3d_texture_merge_alpha (G3DImage *image,
                         G3DImage *aimage);

Merges alpha information from aimage into output image. If image is NULL a new image is created, else image is returned with alpha from aimage .

G3D_FLAG_IMG_GREYSCALE

#define G3D_FLAG_IMG_GREYSCALE       (1L << 1)

The image just uses the red channel for grey value

enum G3DTexEnv

Specify how the texture should interact with other material properties.
