Hi everyone!
Thanks for always answering newbie’s questions like mine so fast and so well! I hope you all had a great weekend!
Let’s see if someone can help on this one:
I got a great big floor with dozens of chairs and sets of tables, and I have tesellated the floor plane, and I have placed a single source light: a spotlight.
However, even though I have tesellated the floor doing like 7 iterations (consisting of a file of 10 mb for a lame floor that doesnt even cover my whole room ), I still get a spotlight light that looks like a circle cutted with a broken scissor by a 2 year-old child who cuts while travelling in a car. (well almost that awful! haha )
Is there an intelligent way for getting a better looking rounder spotlight circle?
Your current code does a vertex based spotlight giving you a change in lighting only at each vertex and making things slightly worse the OpenGL spotlight cone has no soft edge, just an overall exponent and a sharp cutoff.
What you need to do is use projective texture spotlights where you use texgen, a projective matrix on the texture matrix stack to define the cone of projection and an texture image of the light falloff accross the spotlight.
