TBG/Freebuild: Status Update

honestly, I was hoping to have one done this coming week, but I get screwed over by not being able to do anything with the 9 days beginning with thanksgiving vacation.

ah, excellent, we need to work out some sort of engine-source setup w.r.t. to that

Double post, but too bad, because it's kinda cool.
Basically, I'm tired of trying to make other game engines do what I want them to do that they aren't designed for, so I'm writing one myself using C++ and OpenGL, with an embedded Python interpreter for scripting and an HTML/CSS layer for the UI based on libRocket. I've been doing some research on the graphics code I'll need to render LDraw models efficiently, so hopefully it won't take too long to cook up the basic shaders for that.

Very ambitious, elfprince; I hope it works out! I am always very happy to hear that this project is still making progress. Also, if my voxelization project works out, I hope we can extend it to not-LEGO. Smile

Seems like you are going down the path that I took for Redintegrate. I never did get used to any of the other engines I tried Sad

On one hand I'm used to Torque's language and tools and I normally fear change, but on the other, T3D never ran well on my PC to begin with, so I'm rather excited.

Do you think we could get Id/Valve .map support? That would be sweet for those of us that use old school mapping tools like gtk/QuArK/hammer/constructor, which would include all of the mappers Blockland has now abandoned.

FYI, Blender can convert Quake .map files to Collada as well, in case there is a need for another source of conversion.

If you find a reasonable .map loading library, I'll happily plug it in there. Smile

I'll probably support skeletal animations, in some form or another, but I haven't yet planned out what that support will look like. The big thing is that I'll want to design a good API for procedural animations.

Posting spree!

I think I'm about 90% done getting the user action system set up for UI interaction. I won't be surprised if Python's more scope-dependent functionality (as compared to a language like TorqueScript) will force me to do a refactor to eliminate circular dependencies between various modules in the preferences system, but I'm not totally sure.

Other than that, I think I only need to hook up mouse interaction (which will mean a slight refactor of my BoundKey class to push some functionality up an inheritance tree so that BoundKey, BoundMouse, and BoundScroll will all derive from BoundInput).

As far next steps go, after that, I think I'm gonna take a step back from working on UI configuration and get to work on the graphics pipeline and try to test out some instanced rendering to prepare for migrating the LDraw parser over.

Multiple technical posts a day keeps the non-programmers away.

I've decided to go for an "inferred rendering" (click the link if you're interested in graphics-nerdy game engine technology, or just some pretty pictures) solution for the graphics pipeline. Most of the cases where it looks a little ugly are not particularly relevant to our use case (very highly detailed normal maps or lighting, huge numbers of layered transparencies), and it hits the simple setup/good performance sweet-spot between traditional forward rendering and deferred rendering setups.

I'll probably also implement the CHC++ culling algorithm, but I'm waiting to see if I can hijack the spatial hierarchies used by Bullet for physics calculations, or if I'll have to build my own.

[edit]
Also, already up to 2206 lines of code, though about 250 of those are basically just keymappings to convert from glfw keycodes to libRocket keycodes.

I heard you mention you might use Bullet for physics? Also, since you're writing your own engine from scratch, would it be possible to compile for Tegra III Android devices at some point?
