Christoph Oelckers	ef2de97077	- the harmless changes of the failed refactoring of the shader.	2019-10-06 19:32:35 +02:00
Christoph Oelckers	cf30f5560b	- upgraded the polymost fragment shader to GLSL 3.3 as well, removing all legacy features from it. ... The only compatibility mode feature left is the main drawer function using glBegin/glEnd but changing that is not as urgent as the rest. This also cleans up the fog application and adds the exponential fog mode again that somehow got lost over time.	2019-10-06 12:42:35 +02:00
Christoph Oelckers	3d538b4c8f	- use explicit vertex attributes for everything. ... No more glVertex, glTexCoord or glColor calls anywhere.	2019-10-06 10:46:23 +02:00
Christoph Oelckers	71d132b470	- use explicitly declared matrix uniforms. ... The builtin matrices are no longer available in modern GLSL, preventing an upgrade of the shader. Also perform better reporting of shader compilation errors.	2019-10-06 10:19:51 +02:00
Christoph Oelckers	b83349fe6b	- moved the surface shader to the backend and the shader source to the resource file.	2019-10-05 13:09:15 +02:00
Christoph Oelckers	bd4e4834e3	- moved the main shader and its entire uniform maintenance into the backend.	2019-10-05 12:28:08 +02:00
