glodDrawPatch - Draws a specific patch in a GLOD object
void glodDrawPatch(GLuint name, GLuint patchname)
The name of the object to draw
The name of the patch to draw within this object
This call draws a patch in a GLOD object based on the current OpenGL
vertex array state. Only those vertex arrays that are enabled are issued for drawing.
This means that to issue the normals of your GLOD Object, you must have GL_NORMAL_ARRAY enabled.
Having GLOD_VERTEX_ARRAY disabled will disable any GLOD drawing.
This call will not modify your OpenGL state beyond what is listed below:
GLOD does not provide a DrawObject function. This is because you
can duplicate this functionality by performing a DrawPatch
for each patch that you have in your object. This
provides fine-grained control of rendering parameters,
including but not limited to texture and lighting modes.
If you don't need to change your rendering state between patches of your object,
the following utility code may be useful to you:
glodGetObjectIntegerv(MY_OBJ_NUM, GLOD_NUM_PATCHES, &num_patches);
patches = malloc(sizeof(int) * num_patches);
glodGetObjectIntegerv(MY_OBJ_NUM, GLOD_PATCH_NAMES, patches);
for(int i = 0; i < num_patches; i++)
