Thank you for sharing the work. Is there a reason that you choose those values camera['near'] = 1000 camera['far'] = -100 for clippings?

Seem as your question ,it confused me for a long time. T try to set near plane to 0 and far plane to 2000(just same as openGL common used),then I get nothing but black ground…… I check the x,y,z value after perspective project，all of the between -1 and 1（NDC）
