Hi,

thanks for a great engine!
I’ve just started using it today.

Here’s my first question:

I have a skybox with textures of 1024x1024
On one of the textures there is a point at 2D coordinate of say 100,100 that I am interested in. How would I go about and retrieve this point in 3d (world?) coordinates?

Any help or directions would be much appreciated.

A skybox has no radius. It’s always behind no matter what.
You do not need it for this. Just calculate the coordinates of your 2d map to spherical, as the skybox is always at 0,0,0, you will just need to define some radius, transform using camera transform and view.unproject this 3d vector.

Thank you for your answer.

I figured that I could just map the 2d coordinates and multiply it with the camera view distance e.g.

if the texture coordinate is on the negative z side, this is what I do:

x = (min2 + (max2 - min2) * ( (value2dx - min1) / (max1 - min1) )) * -distance
y = (min2 + (max2 - min2) * ( (value2dy - min1) / (max1 - min1) )) * -distance
z = -distance

where min1 = 0, max1 = texturewidth, min2 = -1, max2 = 1

I realize that this is not answer to my original question, but it served the purpose.
