Using Clang compiler can avoid this problem.

How can I set that VS 2019?

It compiled. I tried to load crytek sponza obj as scene. No errors, but screen is just black :/

could you show the console output

that is wierd, the octree is successfully built. Could you change PRIMARY VIEW to ITERATION and post a screenshots

that is too wierd :( . I tested it on windows with GTX 840m and it worked fine... I will try to figure it out sometime tomorrow .. (at school now)

Could you see a red screen like this when replacing "shaders/octreetracer.frag" with the following and recompile it_

#version 450 core
out vec4 oFragColor;
void main() {
    oFragColor = vec4(1.0f, 0.0f, 0.0f, 1.0f);
}

ok, it seems to be a black screen with totally no OpenGL error...... I will do furthur tests when I have access to the windows laptop...... There should be some stupid mistakes.....

AdamYuan commented 4 years ago

Can this executable work: http://adamyuan.xyz/SparseVoxelOctree.exe

trsh commented 4 years ago

Same! Black screen

that means some of my opengl base code dont work on your computer........

AdamYuan commented 4 years ago

There may be some non-standard parts in my opengl basecode. And I suspect the problem is in mygl3/Shader.hpp

Congratulations! Now its Red :)))))

!!!! Sadly I was incorrectly using OpenGL.. Now I had to spend some time to redesign my Shader class

AdamYuan commented 4 years ago

I pushed a new commit, this should be fixed

Jip!
