WebI'm developing for a platform without a math library, so I need to build my own tools. My current way of getting the fraction is to convert the float to fixed point (multiply with (float)0xFFFF, cast to int), get only the lower part (mask with 0xFFFF) and convert it back to a float again. http://learnwebgl.brown37.net/12_shader_language/glsl_builtin_functions.html WebOpenGL Shading Language(GLSL) is a high-levelshading languagewith a syntax based on the C programming language.

WebIn this code, n is the surface normal and l is the unit vector that goes from the surface to the light (and not the contrary, even if it’s non inuitive. It makes the math easier). Beware of the sign. Something is missing in the formula of our cosTheta. If the light is behind the triangle, n and l will be opposed, so n.l will be negative. WebThe fragment shader then selects only those pixels that have one of the texture coordinates with a fractional value below 0.1, painting these with blue color. This last value, 0.1, controls the width of the lines drawn. The vertex shader is the same as above, only the fragment shader needs to be rewritten .
