3D Scene on the PSP

During our university course, one of the tasks was to create a 3D scene on the PSP using only samples provided by the devkit documentation. The original specifications were to include: at least 2 “.gmo” models; a movable camera and lighting. 

My original idea was to create a set of table and chairs and then develop it from there. However once looking for table models, I came across a pool table model. This reminded me of a pool demo I created in XNA to teach myself that library, I decided creating a similar game would help me learn. Even though I wasn’t able to complete my demo, due to limited time on the PSP devkits / other assignments due, I managed to get the basics completed. The table model is available at: http://www.max-realms.com/modules/wfdownloads/singlefile.php?cid=36&lid=819. The models for the pool cue and ball I created myself.

After creating a “loadModel” and “drawModel” method importing models was fairly easy – I could show new models through little effort. I started off by adding in a table and a pool cue. Once this was done, I added lighting from above to simulate the lighting that would generally be on a pool table. I also added a movable camera which involved rotating the world axis on the X and Y plane based on input from the directional pad.

After this I added a ball which bounced around the table, and another which remained stationary. The user could then “hit” the ball using the directional buttons; using the pad would have been a better choice, but as the specifications required a smooth camera I decided the pad would be best for that instead. Once the ball had been hit, the calculations would be done to determine the balls direction. 

I also added some sound in the background as a last minute feature after finding a sample for it in the documentation Sony provided.

I also have more photos avaliable on Flickr

3D Game Engine Using DirectX11 (C++)

Image
This piece of work is what I’m most proud of this semester; it is also one of the projects I had the most fun working on; and because of that, I am currently building upon it and plan to continue over the summer. This is the first time I have ever used a 3D engine, or attempted building my own framework. Framework The engine uses a scene graph to handle the objects in the scene; once the user creates one of the nodes and adds it to the graph, the Initialisation, Updating and Rendering is handled in the underlying framework. I tried to make it so that the user would be able to simply add something to the scene, whilst maintaining as much control as possible. The user is able to create and add a node using 2 lines of code; this then adds the object to the scene graph and everything is handled in the under lying code, the result of this code would load, update and render that object onto the window. The Renderer is what I’ve used as the main DirectX interface...

MIPS Graphics Library

The reason for this task is twofold: first it helped show me show much work the processor had to do to display a simple shape on the screen; it also taught me memory management. The program was written in MARS virtual environment, and uses the Bitmap display to give a visual representation of the code. Each method uses 4 memory addresses to pass parameters, if any more are needed then they are sent to the stack.  The “SetPixel” method is the simplest, it takes the X, Y and colour of the pixel – calculates it position on the screen and then stores the colour into the memory address into the location where the screen gets its information.  The “DrawLine” method uses Bresenham’s Line algorithm. It takes a start point and end point of the line as parameters, as well as the colour. It then works out the gradient of the line, plots the first pixel, and then adds the gradient again to get to the next pixel. This repeats until it has reached the second point. The “Dr...

3D Renderer (C++)

Image
This is a 3D renderer that I wrote in C++ to load in and display “.md2” files, a fairly old format but a good basis into understanding graphics programming. An “.md2” file merely a list of vertices based around an origin, and a set of 3 integers which is loaded in as a polygon. A polygon contains 3 indexes, each point to a vertex in a list, contained within the model. This means that if a vertex is used more than once, it won’t be duplicated. The program started off with “Vertex” and “Matrix” classes which held the instructions to multiply them together; this is the basis of transforming and viewing the vertices on the screen. Once we had these, we could implement the full viewing pipeline, using perspective projection. And after this we could visually display these points on screen. To begin with I focused more on transformations and camera positioning whilst I had the points showing in world space. To visually show the model I made a “DrawWireFrame” method which drew lines...
