Piko3D

Hey everyone!

Here’s another little heads up on Piko3D development and what we’re doing with our spare time 😉
I’m currently still working on the angelscript bindings for the classes we we have so far.  That’s physics, Basic rendering, and resource management, and scene management. Angelscript lets you register your application’s String type, which I recently finished. It works really well! After I’m done with this, I’ll do a little tutorial section about things to look at when you want to implement Angelscript in your engine, so stay tuned for that.

Yesterday, Seriva and I sat together to make a design for Piko3D ‘s rendering system. We had some basic classes that are going to be used for vertex buffers, textures, render targets, and what not, but not a decent structure yet for glueing it all together.  The design is now roughly finished, and we can start implementing it. Hope we can show you some neat renders soon! (it’ll probably take some time still though ;-)) also, since games are already coming out with DirectX 11 and tesselation, we’ve decided to up the spec from OpenGL 3.2 to OpenGL 4.1. This does not mean Piko3D will only be OpenGL 4.1 compatible, but it will be our top priority to get that to work first.

Paramike has made great progress with mulithreading the ODE physics engine. I hope we get the chance to submit our patch to the ODE repository so mulithreading will become easier for all people interested in using ODE for their project.
Collision testing is already multithreaded in piko3d, and paramike was now working on threading the simulation steps and its going really well so far.

Well! That’s it for now!

Hope we can make a new video or have some cool screenshots for you soon.
Till next time!

Hello everyone!

First of all, happy new year to everybody! The Piko3D team have been partying ofcourse 😉 but we also did some Pikoding!

Wracky is busy writing scriptbindings for AngelScript. We chose to write the bindings ourselves instead of creating or using a bindingscreator for maximum control. It may be tedious work, but adding functionality after creating the initial bindings is trivial.

I implemented a threadpool with job scheduling and started distributing scene queries and physics collisions over multiple cores. Next up is the multithreading of physics simulations, but this requires some changes in ODE which may take some time. Since I’ve bought an i7 laptop recently, it’s fun to see 8 cores at work 😀

Expect more progress and perhaps a tutorial soon!

Hey everyone!

Been a while since I posted anything up here, but rest assured, we’re still at work!
In the last few weeks we’ve been busy with some of the more basic functionality for Piko3D.
Problem with such things is that it does not give us nice pictures or movies to show you 😛
So here’s a list of what we’ve done lately

• Basic scene graph was made (more advanced graph in the making)
• Basic frustum culling works
• Wrote my own little INI parser for use with config files.
• Added extra ODE physics joints
• Started with Shader resource management for the renderer
• Objects now have bounding volumes.
• Basic math for intersecting AAboxes, spheres and pyramids.
• Been poking around in SDL 1.3 to see if I could get the mouse to behave!
  (our gateway to OpenGL 3.2 and ES 2.0!)

Aside from that, the team’s struggling with the worldly temptations like Mass Effect 2 and currently Heroes of Might and magic 5 for me 😛
So we take our time, but still have great fun doing this 🙂

Keep you posted!

Hey everyone.

I see that some users come here looking for a 3D engine for Maemo or the Nokia N900.
I made a news post a while back about me looking into the Maemo SDK as a means to port Piko3D to my N900, and I wanted to give you a bit of a status update on what’s going on in that department!

I first ironed  out some minor problems I had with compiling Piko3D under linux on GCC. As said before, I’m now using Premake for managing the pik3D project, which makes all this SO MUCH easier..
The good news is: It builds!

I’ve also found  ports for libSDL,  LibPNG and libODE for the N900.

Here’s what I plan to do:
I first wish to bring Piko3D a bit more up to speed. As some of you may know, Piko3D doesn’t have a proper renderer yet. Scripting is only partially implemented (proper bindings are still missing) and the ODE implementation is not QUITE there yet… There’s no animation system in place yet, and no options for playing sounds.

Since Piko3D uses SDL for it’s basic windowing and messaging, I will be looking at SDL 1.3 for support for OpenGL 3.x and OpenGL ES 2.0. There may still be some problems with initializing SDL 1.3 on OpenGL ES 2.0 but Seriva is looking into that.

I’m currently working on physical joints an motors, of which I hope to post a new video soon. After that, I want to make a setup for Piko3D’s rendering and perhaps we’ll get to some animation aswel… When the basic functionalities are done, I will get back at porting Piko3D to the N900.

So that’s it! Just so you know, It’s still my intention to bring Piko3D to mobile devices, starting with the N900.  Piko3D is still a lot of work, and we do this in our free time and for fun.. so progress might be a bit slow sometimes.

When I feel comfortable that piko3D is turning into an actual product, and things are roughly in place, I will open source the bugger and you can all have a look and help out if you like  🙂

But until then, there’s  still much to be done!

Regards!
Wracky.
