Java: FloatBuffer to OpenGL - wrap() vs. allocate() vs. BufferUtils.createBuffer()

Question

Datasource:

float[] v = { ... };

Working example:

FloatBuffer buf = BufferUtils.createFloatBuffer(v.length);
buf.put(v);
buf.fl         


        

Answer 1

BufferUtils returns a direct buffer whereas the others might not.

You can check the directness of the wrap and allocate methods using isDirect() method. Wrappers are non direct.
