A problem. In OpenGL3.0+ we have to sent a matrix to a shader
float matrix[ ] = {any-16-elements-array};
glUniformMatrix4fv(... , matrix);
I try to do the same in Factor
{any-16-elements-array} alien.c-types:float >c-array glUniformMatrix4fv
and get an OpenGL error. Then I try
{any-16-elements-array} alien.c-types:float >c-array >c-ptr
glUniformMatrix4fv
and get an OpenGL error too.George вт, 1 июн. 2021 г. в 23:21, George Cherevichenko < george.chereviche...@gmail.com>: > How to turn a Factor's 4X4 matrix to C array (I need a pointer float*) in > column-major order? > https://en.wikipedia.org/wiki/Row-_and_column-major_order > Thank you. > > George > > сб, 29 мая 2021 г. в 21:37, George Cherevichenko < > george.chereviche...@gmail.com>: > >> Simple examples without matrices. >> Triangle with glDrawArrays >> https://pastebin.com/QNgGuM2B >> Rectangle with glDrawElements >> https://pastebin.com/cxDvwyqj >> >> George >> >> сб, 29 мая 2021 г. в 02:56, <sf.alexi...@spamgourmet.com>: >> >>> "Generic word my-tuple-field<< does not define a method for the fixnum >>> class.
