Extruding a triangle .
Author
Hi
I have a triangle (3 Vertices) and i would like to write a function that will return 3 other points wich will be the projections of those vertices based on a vector . Any ideas - links ?
Afternoon, Joe Forhens.
Ysaneya meant exactly that.
Add the extruding vector to each vertice in your face.

VecFace.x += VecExtrude;VecFace.y += VecExtrude;VecFace.z += VecExtrude; Cheers,

Thx , do you mean :
Vertex.X += VecExtrude.X;
Vertex.Y += VecExtrude.Y;
Vertex.Z += VecExtrude.Z; ?
And if this is the case , if i extrude the point using a vector 0,10,0 will i get vertices that are just 10 units higher than the ones i originally had ?
Vertex.X += VecExtrude.X;
Vertex.Y += VecExtrude.Y;
Vertex.Z += VecExtrude.Z; ?

Yes. My fubar, sorry.
Is correct.
So if VecExtrude is (7.07, 7.07, 0), then you''d move your face 10 units up/left.

Vertex[0].X += VecExtrude.X;Vertex[0].Y += VecExtrude.Y;Vertex[0].Z += VecExtrude.Z;Vertex[1].X += VecExtrude.X;Vertex[1].Y += VecExtrude.Y;Vertex[1].Z += VecExtrude.Z;Vertex[2].X += VecExtrude.X;Vertex[2].Y += VecExtrude.Y;Vertex[2].Z += VecExtrude.Z; Is correct.
