WebOpenGL consists of two general classes of projection transformations: orthographic (parallel) and perspective. So let's get into detail on both of these! Orthographic Projections Orthographic, or parallel, projections consist of those that involve no perspective correction. Web8 de mar. de 2014 · We can write the above OpenGL perspective process as. [xclip yclip zclip wclip] = Mproj × [X Y Z 1] [x y z 1] ≈ [xclip yclip zclip wclip] All the components of the resultant vector [x, y, z, 1]T will be in the range − 1.0 to 1.0, (ie: normalized device coordinates). The ≈ sign denote division by w component. inc ir
