f4b6763356 Update GLM to latest version (0.9.9.3). This includes GLM's change of matrices no longer default initializing to the identity matrix. This commit thus also includes the update of all of LearnOpenGL's code to reflect this: all matrices are now constructor-initialized to the identity matrix where relevant. 2018-12-30 14:27:14 +01:00

3eaf086897 Spheres model matrix generation fix 
Fix of integer division resulting in some spheres being rendered at same position.
Removed redundant float cast as all operands are being promoted to double anyways.

Fix another graphical error showing a black box

b4982b4611 Fix another graphical error showing a black box 
Is needed in addition to #92 to fix all graphical errors. Happens due to divide by 0 when `roughness = 0.0` and `NdotH = 1.0`.

Also use max to clamp similar fix for specular calculation instead of addition to fix the formula in normal cases

c217609890 Fix rare graphical error showing a black box 
This may happen at certain hard to replicate viewing angles.

Theoretically clamp 0,1 should also be faster since SAT (saturate) is a free operation on output however since saturate only exists on HLSL we are at the mercy of the GLSL compiler to replace clamp 0,1 with SAT. Source: http://www.humus.name/Articles/Persson_LowLevelThinking.pdf#page=22
