bool Ogre::RenderSystemCapabilities::getNonPOW2TexturesLimited | ( | void |  | ) | const

| Are non-power of two textures limited in features? Remarks: If the RSC_NON_POWER_OF_2_TEXTURES capability is set, but this method returns true, you can use non power of 2 textures only if: You load them explicitly with no mip maps You don't use DXT texture compression You use clamp texture addressing Definition at line 345 of file OgreRenderSystemCapabilities.h.

ushort Ogre::RenderSystemCapabilities::getNumTextureUnits | ( | void |  | ) | const

| Returns the number of texture units the current output hardware supports. For use in rendering, this determines how many texture units the are available for multitexturing (i.e. rendering multiple textures in a single pass). Where a Material has multiple texture layers, it will try to use multitexturing where available, and where it is not available, will perform multipass rendering to achieve the same effect. This property only applies to the fixed-function pipeline, the number available to the programmable pipeline depends on the shader model in use.
