![]() ![]() ![]() After that, you have to go through numerous lengthy steps, which are more time consuming in order to find the inverse of a matrix. The inverse of a matrix can only be found in the case if the matrix is a square matrix and the determinant of that matrix is a non-zero number. ![]() But I can't confirm until I try it, because of render monkey bug.Ĭonfirmed, I have billboards working. About the 3 x 3 matrix inverse calculator. Where V represents the inverse of just the rotation part of the View matrix and x,y,z represent the View position. ViewInverse: <-This is what I want to calculateĮdit, I think there's a bug in RenderMonkey, because the Viewmatrix never updates when I move, unless I activate another effect and go back to original. Here is what I know, the names are the "variable semantics": ViewPosition: I can see all the values from within RenderMonkey, but I can’t work out how they calculate the “view inverse matrix”, it’s not the inverse of the view matrix or the inverse of the view projection. I’m trying out a particle system example that came out with RenderMonkey and it uses a “view inverse matrix” to billboard the quads for the particle effect.
