• procedurally generated
• lit with Phong Model

Ben hier nu even mee aan de slag...

Phong

case SPECULAR_LIGHTING: { // Blinn Phong - specular // http://en.wikipedia.org/wiki/Blinn%E2%80%93Phong_shading_model // Viewpoint : CamPos // H = (L+V)/(|L+V|) // -> (NH)^s //s=1.0; Vec3Df h = (vertexPos+CamPos)/(vertexPos.getLength()+CamPos.getLength()); float NdotH = Vec3Df::dotProduct(normal, h); float intensity = pow( NdotH, s ); //std::cout << "s: " << s << " I: " << intensity << std::endl; return LightColor[light] \ intensity; }

procedual generated 3d terrain

I would suggest to take something like this (function: y^2+x^2), in a periodic manner:

More information can be found here

You could for example stretch this area, by tweaking this formula; -(y^2+5*x^2), produces:

This website provides another nice tool to play along with those area-shapes. Like for instance the cos(xy)(x^2-y^2) shape looks also quite nice!
