First Video Demo

And here we are first Tech Demo.

Long Story short.
After hours spend on readings, coding and calculations I have got simple, bit slow but working Smoke effect.
Grid 96^3
FPS 25 – 30 on ATI Radeon HD 5700 Series which lets face it is a crap.
Next step – rewriting code, trying to make it bit more flexible and implement it to polygon based scene.

I’ll make it smoke!

15 Points!

After hours spend on research and readings great publications like: GPU Gems, Coder Mind or Philip Rideout’s, Miles Macklin’s blogs aim of my Honours Project gets clearer and clearer.

I want to create simple Smoke Effect.

“Particle effects like smoke, fire and foam can be efficiently rendered without using hacks. Voxels are also being used by some big Hollywood special effects studio’s to render hair, fur and grass. ” – quote from Ray Tracey’s Blog

All important calculation will be proceed on GPU – I will do my best – using GLSL.

After couple hours spend on learning GLSL I have got that:

Bonsai - Raytracked

Loads of artefacts, however it is not so bad for just couple hours.

Next step will be to implement Perlin noise to get echo – base for my particles.

21/06/11 Update:

Perlin noise implemented.

why?

Why voxels?

I had the meeting with Kevin today,
The objectives has been clarified a bit.. but they are not to easy.. for instance:
“Come up with a Question you want to answer?”

Right so what is my question..

oh and I have set up a wiki.. hope to update it a bit.

Cube ‘n’ Cubes

Cube, Texture, Normals n Light

Over the weekend I have managed to do a bit for my Voxel Engine – well now it will be more like minecraft but hey I am still learning.

Boxes are connected by manager to Entity, Material manager improves performance.

The idea is simple each object is based on bunch of cubes, terrain is based on bunch of objects, that should allows me to implement octree pretty easily.. I hope.

Bonsai v0.2

256x256x256 8 - 9 FPS.. Need Optimisation already...

After hours spent on struggling with the VBO’s and GLSL I have managed to draw my first voxel based model.. the bonsai tree *fanfare*.
File loading time and processing takes about 20seconds, 8.3 FPS without culling or optimisation.. primitive brute force.. get all the points process them through marching cubes algorithm and then draw on the screen.. barbarity I know. but I had to start somehow.
Camera system allow to move around which is kind a nice..

Good night.
