Computed in the last line of the vertex shader:

Code: Select all

return view * model_matrix * vertex_position;

You could use that and do the matrix math to find the screen position.

This is great! I'll credit you and use it in the official repo if you don't mind.

Super cool. I'm doing research for a metroidvania project at the moment and this would be really useful. Are there any plans to have an orthographic viewport? I would like to support simple low-poly objects such as the doors, books, and the background clock tower featured in Symphony of the Night, and to get that pixel-perfect PSX feel orthographic seems to be the way to go.

How does one make 3D objects without typing those vertices for objects?

You don't I mean, you could write a function for simpler shapes, and/or use a model loader for loading in more complex models (which are also made up of tons of vertices anyway).

Edit: lua-obj i'm guessing is an OBJ format loader, and i do recall there being an IQM format loader as well... yep, here: https://github.com/excessive/iqm-exm

I see.

Above comment uses lua-obj, I'll wait for ss3d tp to include that

New version on Github, version 1.3. Obj import added.

Hi.
I forked your repo and made some changes without changing any logic. Mainly its about avoiding globals and removing double calculations. I made a pull request for you. You may also want to look into my branch "folder-test". I moved engine and reader into a engine subfolder. This would make it easier to add more addons to your engine and keeps things sorted in one place.

But how do you rotate the camera? camera.angle doesn't seem to help. Would I have to combine it with camera.pos to get a turn-table animation!
