Hi, I'm trying to learn about the vertices and creating meshes in real time, if I do have traces of my project.

The fact is that VertexColor not work, at least as I hope.

Graphics3D 800,600,32,2
SetBuffer BackBuffer()

Local Camara% = CreateCamera()
Local Luz%    = CreateLight()
Local Plano%  = CreatePlane()
PositionEntity Camara%,0,10,-20
RotateEntity Luz%,90,0,0
EntityColor Plano%, 255,128,64
Local Rueda%  = CreateCylinder(12)
EntityColor Rueda%,255,0,0
RotateEntity Rueda%,90,90,0
PositionEntity Rueda%,0,5,0


Local Brocha% = CreateBrush(255,255,255)
Local Huella% = CreateMesh()
Local Su_Huella% = CreateSurface(Huella%,Brocha%)

Local V0% = AddVertex(Su_Huella%,-2,1,2)
Local V1% = AddVertex(Su_Huella%,2,1,2)
Local V2% = AddVertex(Su_Huella%,-2,1,-2)
Local V3% = AddVertex(Su_Huella%,2,1,-2)

Local Triangulo0% = AddTriangle(Su_Huella%,V0%,V1%,V2%)
Local Triangulo1% = AddTriangle(Su_Huella%,V2%,V1%,V3%)

; Color Vertex.... Red

For vert = 0 To CountVertices(Su_Huella%)-1
	VertexColor Su_Huella,vert,255,0,0,n
Next

UpdateNormals(Huella%)

While Not KeyDown(1)
	
	AppTitle VertexRed(Su_Huella,V0%)	
	VertexCoords Su_Huella%,V0%,EntityX(Rueda%,False)-2,1,EntityZ(Rueda%,False)
	VertexCoords Su_Huella%,V1%,EntityX(Rueda%,False)+2,1,EntityZ(Rueda%,False)
	
	MoveEntity Rueda%, .05,0,0
	
        UpdateWorld 	
	RenderWorld
	Flip

End

Hi, you need to set flag with EntityFx

EntityFX Huella%,2

thank you very much, hopefully as I go with this, have if I create a mesh in real time traces showing the wheels on the ground.

If you mean wheel tracks, I'm sure you're aware of copyentity...?
Then you can make just 1 real good section and replicate it?
I dunno... Segment edges wouldn't line up around curves though...
