Texture mapping
The command Create texture map allows you to create textures for your mesh model.
Preview resolution
Firstly select a camera to specify a viewpoint from which the texture should be created and parameterized. The resolution of the camera can be changed here.
Update preview: creates a preview of the texture from the selected view point and projection. This is a simplified image and does not represent the full quality of the final texture
Projectors to blend
You can load simultaneously more projectors that project photographic color on the same mesh.
The maximum number of simultaneous projectors supported depends on your graphic card. Check at Help > Hardware info | GPU and graphic functionalities what is its value.
Successively, you can create a texture.
A texture is a particular image that, mapped on your mesh, gives to it the color. The texture is calculated by blending together all the color coming from the projectors.
Create single texture map: create the texture by blending the checked projectors. An image of png format is created, plus a 2f file that stores the computed texture coordinates for the mesh vertexes, which is listed in the Mappings. Check if shadows must be computed.
Mappings
- Remove: remove the selected mapping from the list
- Remove all: clears the list
Re-cluster: create a new triangle meshes model where the listed mappings are used to re-arrange the triangles in a new set of submeshes that map the desired textures. Each triangle is mapped with the best texture quality available by computing the best texture projection among all. The model is automatically added to the project.
In the contextual menu of meshes the command Sample texture as vertexes is available.
It assigns to the vertices of the mesh a color obtained from the corresponding pixel of the texture.
