Transposed matrixes not supported on every system

[mkalte666]

Hello,

i am currently writing a rpg engine in D. I recently ran into a confusing problem caused by the following:

In older OpenGL versions, especially when you only have access to ES Core 2.0 contexts, glUniformMatrix only accepts GL_FALSE as transpose argument and otherwise generates a GL_INVALID_VALUE [1]. While i can simply call transpose() on the matrix, thats extra-stuff that needs be done every time i submit matrixes to the pipeline.

Is there an alternative way?

Unfortunatly not, I made a (in hindsight) bad decision in choosing the matrix layout. I think @extrawurst is working on a column major Matrix!() implementation, until that is done there is unfortunately no solution other than transposing manually.

Hmm ok. Thanks for the reply though, ill take a look at this in the future.
