Hi,
I have the following code snippet :
void set()
{
GLfloat[] data = [
-1.0f, -1.0f, 0.0f,
1.0f, -1.0f, 0.0f,
0.0f, 1.0f, 0.0f,
];
glBindVertexArray(mVAO);
glBufferData(GL_ARRAY_BUFFER, data.sizeof, cast(void*)data,
GL_STATIC_DRAW);
}
And I ask my self about the memory management of data, as my data
array is statically initialized is it allocated on stack?
Note that if you can define the data array as immutable, you save on
heap memory allocation + copying (LDC, from -O0):

Thank you for the tips.
