Understand theory and applications of 3D

Zac Argo

Applications of 3D:

3D is everywhere films, TV, cartoons etc.. Almost every single film released on the big screen nowadays is also released in 3D. However the first ever 3D film was released on the 27th September 1922 believe it or not. Many childrens cartoons are rendered in 3D now. Most games are 3D as it adds depth and realism to the game.

Displaying 3D polygon animations:

Many things use Direct3D to display 3D polygon animations. Direct3D is an API for Microsoft Windows, it’s used to render 3D graphics where performance matters, such as games.

A graphics pipeline is used in games and it is a sequence of steps used to create a 2D raster representation of a 3D scene. This includes modelling, lighting, viewing, projection, clipping, scan conversion, texturing and shading, and display

The two most popular methods for calculating realistic images are radiosity and ray tracing. The difference between the two is the starting point. Ray tracing is a very good method at simulating specular reflections and transparency. Radiosity stores illumination values on the surfaces of the objects,as the light is propagated starting at the light sources. These are rendering techniques.

This is rendering, the process of changing a 2D image into a 3D one.

Geometric theory

Vertices: In geometry, a vertex a special kind of point that describes the corners or intersections of geometric shapes

Lines: A line is a collection of points along a straight path that goes on and on in opposite directions. A line has no endpoints. A line segment is a part of a line having two endpoints.

Curves: an object similar to a line but which is not required to be straight.

Edge: In geometry, an edge is a particular type of line segment joining two vertices in a polygon.

Polygons: Polygons are many-sided figures, with sides that are line segments. Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. A regular polygon is one that has equal sides.

Element:

Face: In solid geometry, a face is a flat (planar) surface that forms part of the boundary of a solid object; a three-dimensional solid bounded exclusively by flat faces is a polyhedron.

Primitives: The term geometric primitive in computer graphics and CAD systems is used in various senses, with the common meaning of the simplest geometric objects that the system can handle

Meshes, for example wireframe:

Coordinate geometry (two-dimensional, three-dimensional):

Surfaces:

Mesh construction

Box modelling

Extrusion modelling

Using common primitives, for example cubes, pyramids, cylinders, and spheres.

3D development software

Software, for example 3D Studio Max, Maya, Lightwave, AutoCAD, Cinema 4D,

File formats, for example 3ds, .mb, .lwo, .C4d, and plug-ins.

Constraints

Polygon count, file size, rendering time.

Unit 20 Assignment 3 - Blackjack game / Wayne

Blackjack game assignment

Zac Argo

Task I: Mobile gaming

The Blackjack game I am creating will be able to be shrunk down to fit on an iPhone 6 screen. The iPhone 6 screen is 4.7” and it runs on iOS 8. The specifications required to run my game won’t be that high meaning that I won’t have to change too much of my game – just the sprite sizes. Most computers nowadays are essentially portable PCs; the iPhone 6 will be able to run my game.

The game will be played by touchscreen, I will leave the buttons you need to press a little bigger than the other sprites so people with big fingers can touch them easier. This will be done by setting virtual buttons over an object. I will have mute, play, pause, stick, twist and volume on and off buttons. It will be the same as my PC game just scaled down. This is done through adding a script, Display_set_gui_size [67, 138]. Using the code virtual_key_add(x, y, w, h, keycode), x and y being the coordinates that the key on the screen, w and h being height and width and keycode being the key that is activated when you press the button.

The game will look essentially the same as on PC, only difference is it will be smaller and touch screen.

This is what it would look like.

This is how I’d convert it (this is an option in GameMaker).

Task II: Web gaming

For my web game I’ll have to scale up my sprites as it will be bigger than my game.

To put my game on a website I’d have to embed it. Web based games often work on tablets and phones but it’s usually better on a computer as it has higher specs.

This is how’d I’d convert it (this is an option in Game maker).

Unit 73 Assignment 2

Sound for Computer Games 

Zac Argo

Plan:

My plan is to create a western themed Blackjack game. I've taken inspiration from spaghetti westerns, particularly Black Jack. 

The sounds I'm going to create are:

• Cards shuffling
• Glasses being put down (drinking)
• Handing out of the cards sound
• Yeehaw sound (when you've won)
• Whip crack sound (when you lose)

• One sound track

I will be creating the sounds myself, recording them with a Dictaphone. I will then edit the sounds using Audacity, following that I will add them to my game (in GameMaker) at appropriate points correlating to what I described in my earlier bullet points.

I will create my soundtrack in GrooveShark. Using the array of tools and instruments it provides I believe I will be able to create an acceptable sound track for my Western Blackjack game. After I've created my sounds in GrooveShark I will edit it in Audacity, to edit any mistakes and loop so it's long enough for my game.

Creating:

Aforementioned I am creating my sounds using GrooveShark and editing my sounds using Audacity.
Here is a screen shot of me editing my track using Audacity.

I have uploaded all the sounds I've created here:
Zac Argo sounds for Josh Rai Unit 73


I made the sounds around the library and at home, mainly at home. The sounds I created at College were recorded by a Dictaphone, the ones at home were recorded using a microphone.

Proceeding this I uploaded the files to my computer and edited them accordingly (if they needed to be).

Both devices that I recorded with allow you to record in both mono and stereo. I recorded all my sounds in stereo, however one of the sounds (card dealing) I wish I could have made it go from left to right [sound in your ears].


I persevered to make my sounds as original as I could, however, in my opinion, the western sounds are quite restricted as it was a period that only revolved around certain topics (eg. gun showdowns, horses, carts etc.) therefore it was hard to make a sound that wasn't extremely dissimilar than the next western piece.

As well as looping I edited my track to highlight a certain sound. I made my track go quiet and added in a "YeeHaa!". I did this so the "YeeHaa!" was a prominent and memorable in an otherwise forgettable piece.

Evidence:

Evaluation:

I think my sounds are okay but due to the sprites that are in my game there is no context. Essentially it's western sounds on a blank canvas. I could have developed my sprites a lot more (eg. wooden table, sprites with cowboy hats, shot glasses on the table), I believe my sounds and sprites would have helped each other out if I put more effort into my sprites. That being said I believe my sounds could have been a lot better, more specifically my soundtrack (not the sounds [card shuffling etc.]) if I had put more effort into developing my soundtrack.

As far as hardware and software are concerned I'm certain I used the best quality equipment and software that was available to me. If I practiced more with said equipment/software I am adamant that the quality of my production skills will improve.

To conclude the sounds work as intended although the sounds aren't the epitome of effort-driven work. I believe with more practice and effort my sounds/game could have been a lot better than it is.

Unit 72/22 - Computer Games Design

Zac Argo

The game concept is simple - BrainBox (the protagonist) has to go level-by-level collecting gems and answering math questions to advance. 

The design didn't take too long, ultimately I decided to go with a pretty neutral coloured protagonist, I decided to give him a drill to keep with the theme of my game.

One of the main problems I encountered was layers. I had multiple problems where the player would be stuck between walls presumably because the (BrainBox) sprite was on a lower level however, this was simply fixed by putting the sprite on a lower level than the walls. Another problem was you could simply dodge the question at the end of the level; it was fixed by putting it on a higher layer than everything else.

Playing the game required you to use standard WASD (W UP, A LEFT, S DOWN, D RIGHT).

At the end of the level you're asked a math question that get progressively harder the higher the level. It's multiple choice, get it wrong and you have to restart the level, get it right and you advance.

I went with a simple level design just simply for time reasons, both sprites and levels.
