The printable version is no longer supported and may have rendering errors. Please update your browser bookmarks and please use the default browser print function instead.
This feature is utilized in a number of visualization approaches: triangles with individual textures for each vertex, which are interpolated during rendering.
Syntax:
MESH_TRIANGLE:
triangle {
<Corner_1>,
<Corner_2>,
<Corner_3>
[MESH_TEXTURE]
} |
smooth_triangle {
<Corner_1>, <Normal_1>,
<Corner_2>, <Normal_2>,
<Corner_3>, <Normal_3>
[MESH_TEXTURE]
}
MESH_TEXTURE:
texture { TEXTURE_IDENTIFIER } |
texture_list {
TEXTURE_IDENTIFIER TEXTURE_IDENTIFIER TEXTURE_IDENTIFIER
}
To specify three vertex textures for the triangle, simply use texture_list
instead of texture.
