visualization

[Elmar]

Hello,

I have a 3d object.I want to include this object to my program as mesh and create visualization of this object. But this object contains of some parts.(for example cube, sphere etc.) How i can to set different textures to different parts?

Please, help me.

PaintEntity( FindChild(model,"meshname"), LoadMaterial("abstract::matname.mat") );

I can add this object as one mesh and apply texture to it. But I want to apply custom textures to custom parts of this mesh.

Lumooja showed you that way, have you tried it ?

I think he wants to paint a surface with a material.

PaintSurface might be what you want. Here's an example function that utilizes it (in Lua, but C would be basically the same):

 

function makeUniqueMesh(ent, meshname)
local orig_mesh = ent:FindChild(meshname)
local new_mesh = CreateMesh(ent)

for surface_index=1, orig_mesh:CountSurfaces() do
	local orig_surface = ent:FindChild(meshname):GetSurface(surface_index)
	local new_surface = CreateSurface(new_mesh)

	for i=1, orig_surface:CountVertices() do
		new_surface:AddVertex(orig_surface:GetVertexPosition(i-1), orig_surface:GetVertexNormal(i-1), orig_surface:GetVertexTexCoords(i-1,0))
	end

	for i=1, orig_surface:CountTriangles() do
		new_surface:AddTriangle(orig_surface:TriangleVertex(i-1, 0), orig_surface:TriangleVertex(i-1, 1), orig_surface:TriangleVertex(i-1, 2))
	end

	PaintSurface(new_surface, GetSurfaceMaterial(orig_surface))
end

new_mesh:SetPosition(orig_mesh:GetPosition(1),1)
new_mesh:SetRotation(orig_mesh:GetRotation(1),1)
HideEntity(orig_mesh)
UpdateMesh(new_mesh)

return new_mesh

end
