Arguments

obj, tex_obj Pointers to a GXTexObj structure
min_filt returns the reduction filter from the texture object
mag_filt returns the magnification filter
min_lod Returns the minimum LOD value
max_lod Returns the maximum LOD value
lod_bias Returns the LOD bias
bias_clamp Returns the LOD bias clamping parameter
do_edge_lod Returns edge LOD status
max_aniso returns anisotropic filtering setting

Return Values

The GXGetTexObjLODAll function returns void. The other functions return data values as indicated by their names.

Description

The GXGetTexObjLODAll function returns the LOD-related parameters described by a texture object. Also listed are functions to get each data item individually. Texture objects are used to describe all the parameters associated with a texture, including size, format, wrap modes, filter modes, etc. Texture objects are initialized using either the GXInitTexObj function, or for color index format textures, the GXInitTexObjCI function. The LOD-related parameters are set using the GXInitTexObjLOD function.
