I figured I could do this using the fragment shader. Essentially, I'm masking each corner with a circle that is r units away from each wall for that corner. Web30 de dez. de 2011 · As pointed out above, use alpha blending for GL_LINE_SMOOTH. Call glLineWidth to tweak the thickness when wider than 1px (with alpha=1.0). To draw lines that appear thinner than 1px, scale the alpha, e.g. glColor (1,1,1,0.5) for 0.5px wide lines. glLineWidth does not accept values smaller than 1.0 (=1px width).

Lets say that you want to find to normal for the vertex i (i is a 2D/3D vector), where i1 is the vertex after i and i2 is the vertex before i, this is what you do: Create two vectors, v1 and v2. Set v1 it to i1 - i, and set v2 it to i2 - i. Create another vector called v3 and set it to the cross ...
