android - Unexpected gl_stack_underflow error -



android - Unexpected gl_stack_underflow error -

i working on little game uses opengl.

i getting gl_stack_underflow error. have gone through code, , there 1 glpushmatrix each glpopmatrix. ideas else causing error?

did maybe a

glmatrixmode(gl_modelview); /* ... */ glpushmatrix();

"balanced"

glmatrixmode(gl_projection); /* ... */ glpopmatrix();

it matters matrix active @ time of push/pop operation.

anyway, shouldn't utilize opengl built-in matrix operations @ all. utilize glm, eigen or linmath.h build matrices part of programs info structures , load matrices require glloadmatrix or, when go shaders, gluniform.

no, opengl built-in matrix operations not gpu accelerated, there's no benefit @ in using them.
