Gravity

3D OpenGL engine for Go

Building

Under the developing directory is the project code I use to test as I work on the engine itself. I keep it always buildable when commiting. To try it out, run the command gdt rundevapp or ./gdt.bash rundevapp

Current Development

The very latest progress demo can be viewed on youtube: https://www.youtube.com/watch?v=sHncnFAnDek

Summary: Terrain generated by World Machine loaded into engine. I am still working out exactly how to texture the terrain mesh correctly with the splat maps and height maps.

Next Development

Next on the todo list is bolting on a physics engine. Currently I have a prototype of bullet3 working well enough and if nothing changes, I plan to integrated bullet3 very soon.

On the horizon is to begin implementing a proper scene graph which will pave way for ECS implementation.

Gravity Development Tools

For consistent tooling purposes across platforms all common Gravity development tooling is being put into ./developing/tools as go source files. You can run these tools by using go run ./developing/tools <command>

Currently available GDT commands:
apitrace - trace full opengl state and opens qapitrace gui (requires apitrace)
depgraph - graphs package dependency relationships of Gravity (requires graphiz)
genversion - generate the version.go source file for Gravity (requires git) rundevapp - go run's the developing/experimenting program under ./developing
