How can I cast a []byte to []mgl32.Vec3?
Hperigo opened this issue · comments
Hi there, thank you for this wonderful lib.
Im trying to implement the glMapBuffer function and I’ve managed to retrieve the vbo buffer similar to what’s described in here: #28
My question is, how can I cast the []byte to a []mgl32.Vec3?
gl.BindBuffer(gl.ARRAY_BUFFER, vbo.VboHandle)
ptr := gl.MapBuffer(gl.ARRAY_BUFFER, gl.READ_WRITE)
return (*[1 << 30]byte)(ptr)[:length:length]
thanks!
You can either use type conversions, or use unsafe
package to try and cast more directly.
See the source of https://godoc.org/golang.org/x/mobile/exp/f32#Bytes for an example of the conversion approach.
I'm going to close this thread since there was no further and @dmitshur's comment looks to answer the question.
