geo-vtx-fmt

Description

geo-vtx-fmt tests many of the basic functionalities of the graphics pipeline. This test uses the vertex coordinate, color, texture coordinate 0, and geometry (for example, a normal line) attributes. These four attributes are tested with theGXVertex, GXSetArray, GXSetVtxDesc, and GXSetVtxAttrFmt functions. This demo also tests alpha blending (all cubes have an alpha gradient on one face when the color is valid) and all possible geometric primitives.
