maj00r	8df87d42cf	fix(shaders): the highlight of the sun is multiplied by the cosine of its light, so surfaces no longer glare milky white under a low sun; headlights light a surface with 1.35 of its diffuse colour and add a GGX highlight of their own scaled by specgloss and param_specular instead of multiplying the whole light by one plus param_specular; normalmap, parallax, detail, shadowless, sunless and default_detail materials read param_glossiness as a Phong exponent, roughness = (2 / (n + 2))^1/4, instead of 1 - 1/n or a fixed mirror	2026-10-14 22:11:06 +02:00
maj00r	3d6a465570	fix(shaders): parallax mapping of the opengl33 materials is shared by the four parallax shaders in parallax.glsl and samples its depth with the gradients of the surface instead of letting a loop of varying length pick the mip level, picks the number of layers by the angle of view alone and refines the hit with a binary search instead of one linear step, so stones near the camera no longer show combs of layer slices; it fades out between 60 and 100 m instead of stopping at a hard line and fades out at grazing angles, and the simple offset without extra effects no longer divides by an unbounded cosine of the view	2026-10-14 14:23:52 +02:00
antonisauren	d1ecbdc8ff	Sim (#11) ... * Wheels animation distance changed to 200*D*LODbias * Fixed spelling error in event syntax; old one remains for compatibility. * Spelling error left in log text * Zamiana metalic na floata z wazonym efektem. # Conflicts: # shaders/light_common.glsl * Detail normalmap shaders @Jan21 * Explicit type conversion * Leftover metalic as bool * Syntax error * Normalmap sampling inside ParallaxMapping function	2021-01-23 22:24:14 +01:00
