Texture Tutorial

From K-3D

How do I texture a scene?

K-3D texture mapping is in its infancy, so we'll texture the easiest object : a rectangle.

• Create a PolyGrid :

• Filter it with TextureMap object to create texture coordinates : Filter menu -> Mesh -> TextureMap

(In version 0.5.0.40 this menu does not exist, so I think this tutorial is outdated).

• Choose +Y Axis (since PolyGrid expands in +Y and +X directions), and choose a New PlanarMap in Mapping Type list.

• Create a BitmapReader bitmap object (Create menu -> Bitmap -> BitmapReader) :

• Then choose your texture file by clicking on the browse button " ... " :

• Edit a surface shader, if you worked with K-3D default document there's one named Surface Shader, and choose k3d_painted_plastic instead of k3d_plastic :

• Then search for texturename parameter and choose New [[RenderManTextureMap]]; then click on the Input plug and connect it to [[BitmapFileIn]] : output :

• Render!

Notes :

• This process requires the Tiff plugin: it converts all input textures to the Tiff format which is understood by common RenderMan engines.
• Above instructions yield the following Visualization Pipeline:
