fragPosition was multiplied by mvp*instanceTransform, but it should only be multiplied by instanceTransform. Compare to lighting.vs, there we only use mvp for gl_Position, but matModel for the fragPosition.
* basic pbr example
pbr implementation includes rpbr.h and few shader files header only file, which self contain everything needed for pbr rendering. Few textures and one model of the car which is under free licence which is included inside basic_pbr.c example file currently supported shader versions are 120 and 330 , version 100 has small issue which I have to resolve
* Unloading PBRMAterial
I forgot unloading PBRMaterial
* fix small issue with texOffset assigment.
value was Vector4 at first but I found out it would be unclear for and users, so I change to have two Vector2 instead, but forgot to assign offset .
* Changed size of textures and file name changed
Changed size of textures from 2048x2048 to 1024x1024 and file name changed to shaders_basic_pbr.c ,
Added the function PBRModel PBRModelLoadFromMesh(Mesh mesh);
but GenMeshPlane(2, 2.0, 3, 3) culdn't be used because it crash once GenMeshTangents() is used with that plane mesh
* Simplify POI selection
* Improve mouse logic
* Add colour cycles to the shader to show finer details. Works well with high iteration numbers
* Testing things...
* Actually fix zoom. Also allow user to reset camera with 'R'
* Reset max iterations
* Tidying & comments
* Revert to original if statement
* Make mouse logic more readable
* Style conventions
* Coding conventions - f postifx on floating points
* Missed a few f postfixes
* Removed Unused Uniforms
uniform vec3 viewUp;
uniform float deltaTime;
* Removed Unused uniforms
uniform vec3 viewUp;
uniform float deltaTime;
* Updated Source
Added - #define PLATFORM_DESKTOP line for desktop users.
This now will correctly find the proper glsl version for the raymarching.fs file.
Removed - Uniforms --> deltaTime and viewUp. Including the code that was setting them.
They were never used and they were triggering a log warning.
Removed - The const from both screenWidth and screenHeight.
Now they can be used to update the shader resolution when screen is resized.
NOTE : This is a quick fix and probably not the best idea.
Added - IsWindowResized() to check if screen is resized.
If window is resized then width, height and shader resolution are updated.
Changed - MIT tag at bottom right color value to BLACK. Now it's easier to see.
* Closer Match to original code
* Removed the PLATFORM_DESKTOP Define
Now dividing by the zoom instead of multiplying (in the shader), so zoom works as expected. Also zoom increase/decrease is now scaled depending on the current zoom.
