[School Project] Rendering Engine

[Boogy]

My very first serious post here

For a school assignment we have to make a 3D rendering engine with either DirectX or OpenGL.
I decided to go with DirectX

The minimal requirements for the final assignment are:

• Display a 3D model with animation
• Basic particle effects
• Basic terrain with a single texture

This is what I have at the moment:


A textured rotating cube

The next thing on my todo list is model loading.
I keep you updated in this thread when I have something new to show

TODO:

• Load MD5 file and display model
• Animation
• Terrain
• Particles

That's what I call a fun assignment! Nice start

Last block we had to make a software rasterizer which was pretty fun.
I managed to render 95k of polys on 20 fps on my laptop, Intel Core2Duo T6500 @ 2.1 GHz

Out of interest, how long do you have to complete this assignment.

One block, which is 7 weeks of lectures and 1 week to study for your exams so in total you have 8 weeks to complete the assignment

Particle effects shouldn't be too much of a hassle, and rendering terrain from a heightmap shouldn't provide too much difficulty either, so good luck with this, I'd bet it'll look really cool when it's done!

Looks good so far, show us the finished product when you're done!

I want you guys to meet bob:



Bob is a MD5 model that currently resides in my rendering engine

MD5 sexy!

Hi Bob! Bob, you should really change your name to something a bit more.. original.

I finished my terrain loading today.
It takes an 8 bit raw heightmap and converts it to a terrain
I also had a bug which turned it into some sort of minecraft-like terrain :P

EDIT: If you want to see for your self you can download the application here. Use the left mouse button to rotate the camera and move with w,s,a,d. Shift to move twice as fast.

Multi textured bugged 'terrain' :P


Multi textured normal


Single textured ''bugged'

BTW I am almost done with my particles. I have a firework particle effect and I can generate snow and rain

Thats pretty sweet, can we see a wireframe closeup on the terrain?

Sure

That was quick

I was just asking 'couse the terrain looked blocky, but now that I think about it the triangle placement shouldn't matter that much, however I think it would look smoother if the height of each vertex were calculated as bilinear (which I'm guessing it's not and that the height map's dimensions are smaller than the terrain's).

This might help wiki.

It seems easy to implement but I can't speak from specific experience here.

Triangle placement in a pattern like this:

Code: Select all

|\|/|
|/|\|

Would make it more well rounded, but probably doesn't have the same impact as the bilinear thing.
