I am not sure if there is a word for what I am trying to do. What I am trying to do is to map a texture on a rectangular plane (which works). But I want to be the texture and the plane to be partly transparent to form randomly formed objects.
I think that I could use the alpha value to do this.
But how do I generate and store the alpha values for existing textures. Are there any simple examples for this? Or is there perhaps a better way to do this?
I have transparent effects now, but the problem is, that the effect I have is always affects the whole image.
I just want to habe partly transparent images. I set the alpha values in this way:
Assuming you want to rotate your texture mapped rectangle then you can set your rectangle’s metallic properties ( Ch 5 red book) where when a side of it moves away from fixed light position, can fade and the one that is near is bright.
Thank you for the help. Now it works. I think it was a problem of OpenGL settings. I will check it later.
I have been at least ten times on the billboard page you posted but only read the first line: " Billboarding is a technique that adjusts an object’s orientation so that it “faces” some target, usually the camera. " So I thought it is a kind of camera adjusting…
I’ve the same problem. I want to fade in text with transparent background ( or tree same as above ) Now I get all texture region white instead of only seeing the white writing(tree whatever)
Could you give me some code snippets for help?
Many thanks
