Affine texture mapping : Subdivide Mesh


Af fine map indeed


Another bug I  encountered in my previous project was when using the PSX shader on large surfaces the warping became severe which was disorientating while playing. This is because the affine mapping that the shader does to emulate the affine mapping the PS1 did, approximates the positions of vertices in screen space meaning that if the vertex in question is far off-screen the approximation becomes more inaccurate meaning that if you subdivide the meshes into smaller triangles the effect is drastically diminished.

2D Side Scroller : Bugs

They're everywhere! Run for your lives! I kept a log of bugs I found so I remembered to fix them later and to remember the solution should they crop up again. This really helped, as a couple of times I got the same issue long after I encountered and solved it the first time. it was simple to look at my notes and be able to see that the problem was I had missed setting up a component or that it was a unity issue that would be solved by simply restarting the program.

Art and Design Exercises : Decontructing Art into Basic Shapes for 3D Modeling, Glastonbury Dam

The Poäng of Art Glastonbury Dam, By Tyler Edlin, can be broken down into one large cube for the central building of the castle with another rotated and reduced for the roof. The wall is comprised of 4 cylinders with cones on top for the rooves. The tunnel section of the wall could be constructed from rectangles and cylinders using the difference boolean. For the details on the turrets themselves such as the wooden beams, I would use rectangles sunken into the surface to create the depth present in the facade. Alot of the surface detail is heavily repeated on a micro-scale and then on a macro-scale so I would probably try to create a detailed wall for example by creating the largest parts first then cut to get the tunnel, then add the rectangles to make up the supports on one small section and copy that across its breadth. Finally, I would then copy the whole thing for the other walls and make any changes that need to be made to distinguish them. using the same technique I would make t

Board Game : Development pt 3 Review

Doom  (and not the good kind) I had a host of problems all arise at the same time near the end of this project. Some were very much miscalculations on my part as to the time certain tasks would take and others were simply out of my control although I should have given myself more wriggle room to work with. Firstly I vastly underestimated both the time I would need to make the board in adobe illustrator, in addition to vastly overestimating my competency with the program. Every minute of creating the 'final' version of the board you see here was agony. The circles flatly refused to centre on each or anything else for that matter, making it near impossible to create the segments around the edge to create the tiles the players move on. This also meant that the coloured rooms that player are meant to pick items up from are not close to being lined up. All of these horrible errors could have been avoided had I done two things. TWO THINGS I WILL DO NEXT TIME!. Thing, the first: Creat
