Make a logo for overlay with a mesh
I wanted to learn about meshes, and so I figured I would help Almar with a suggestion I made offline.
You guys killed me with your gradient. I got all the coordinates by writing down the numbers from the svg using inkscape. You even had one for the blue....
I don't really like it since I wish it was pixel perfect. I also want to make it easier to use in the examples. currently, I still feel it adds too many lines of code in the example.
I wish I was able to make it a point material, and then we could just place it anywhere, and ensure that it is pixel perfect on the GPU. All gradients included. That would require a custom shader, but it would be pretty cool!
I guess you could render it as a sprite via a texture. But obviously your approach is going to look crisp, no matter what. Cool stuff!
One challenge I faced with rendering logos with transparency as images is that it really depends on the blend mode to not hide the stuff behind the transparent region. I'm hoping that with a mesh this is less of a concern.
The chosen colors mean that it looks great on the many example backgrounds without any outline.
The one thing i'm worried about is that the new function
gfx.render_with_logo
removes the call
renderer.render()
or
renderer.flush()
from the examples. For this reason, I didn't want to add this to the tutorial examples. But maybe there is a way to do it well.
