Description

A lightweight, elegant 3D game engine

Instructions

What's New

_____________________

Version 1.2

  1. Framerate has been doubled and possibly tripled, especially for DLC users. The engine runs incredibly incredibly fast for users that have purchased the SmileBASIC DLC!
  2. SIM.3D no longer needs any other program slots other than 3. So this update makes it a lot more compact and simple.
  3. Hue, saturation, and value are now optional by using HSV(H,S,V) just like RGB(R,G,B). Objects only need a single color value to be initialized. So #RED, #GREEN, #BLUE, etc... can work too.
  4. Field of view (FOV), world scale constant (WSC), and the cutoff ratio (CUTOFF_RATIO) are modifiable. Cutoff ratio is the ratio between the camera and the object of focus in which polygons will no longer be drawn. Default is 0.5.
  5. Lots of new functions that give more power to the user, such as finding the closest/furthest objects to a point, and making an object rotate to face a given point in the world.
  6. Behind the scenes optimizations for maximum performance.

Version 1.1

  1. DLC is fully implemented! The engine runs much smoother when the Advanced Sound DLC is purchased, the application now only needs to run a few ARYOP operations each frame.
  2. Performance without DLC has also been improved, but DLC gives much higher performance.
  3. Circles have been removed, and re-implemented as triangle objects. Now that there is complete consistency with objects, huge performance advancements have been made.
  4. The flickering graphics bug has been targeted and removed. Graphics feel cleaner with modified algorithms.
  5. Example programs have been modified a little bit. Please feel free to view the code for those, and use them to implement your own games. I do not require any credit. Everything is free for everybody.
  6. Triangles are now sorted by the furthest away Z point.
  7. CIRCLE functions are now called SPHERE functions.
  8. All future updates from this point forward will minimize the modifications required for a game to run on the updated engine. Any modifications required will be listed down here for you.

Version 1.0

  1. Application is stable.
Notes This application was designed specifically to teach the idea of 3D game design. While this engine was built with simplicity in mind, it was also built to maximize efficiency and minimize the computation required to display good looking graphics. I thought SmileBASIC could use a well documented, stable, high performance 3D engine. This will hopefully allow people to make more 3D games, I don't ask for any credit, I'm just trying to help and teach you guys some cool topics that will set our programming community apart from others. Use the comment section below for help, or if you have any questions, I'll be glad to help! To use this engine, simply add this to the first line of your code, before everything else PRGEDIT 3 EXEC "PRG3:3D.ENGINE"Doing so will load the 3D engine into program slot 3, then insert the code from program slot 1 into program slot 3, then execute itself. The most basic application to rotate a cube in the center of the screen is as follows: PRGEDIT 3 EXEC "PRG3:3D.ENGINE" VAR C=ADDCUBE(0,0,0,1,1,1,#GRAY) @LOOP VSYNC BUFFER GCLS ROTOBJ C,0,1,0 RENDER GOTO @LOOP There are a few things to be aware of before diving into the 3D engine
  1. One in-world unit is the equivalent of 50 pixels. Adding a scale definition like this makes the game feel more realistic.
  2. When working with SIM.3D, you must work in the default program slot 0, you will need to save every time you run the code. Any errors can be traced to your code in program slot 3 where the actual engine is.
  3. Or you could work directly in the 3D engine and avoid the use of the loader. There's a spot in the beginning of the code dedicated for user programs to go.
  4. Every object is composed of triangles. If a triangle is defined clockwise then it will be visible from the outside of the object. There are preset objects to make this easier to work with.
  5. So triangles can only be seen from one side (for higher performance), using STRETCHOBJ with negative values to stretch an object inside-out will let you see the object's back faces instead of front
  6. Every object is given an index. This index will never change until the object is deleted, in which case the ID will be given to the next future object to be defined.
Here are the preset object definitions:ADDCUBE(X,Y,Z,LENGTH,WIDTH,HEIGHT,COLOR) 'CREATES A RECTANGULAR PRISM, RETURNS ITS INDEX ADDSPHERE(X,Y,Z,RADIUS,COLOR) 'CREATES A SPHERE, RETURNS ITS INDEX IN THE WORLD ADDPYRMID(X,Y,Z,WIDTH,HEIGHT,COLOR) 'CREATES A PYRMID, WHERE THE BASE OF THE BOTTOM IS X,Y,Z 'RETURNS THE OBJECTS INDEX ADDDIAMOND(X,Y,Z,WIDTH,HEIGHT,COLOR) 'RETURNS THE OBJECTS INDEX ADDCRYSTAL(X,Y,Z,WIDTH,HEIGHT,COLOR) 'RETURNS THE OBJECTS INDEX ADDSKYBOX(X,Y,Z,LENGTH,WIDTH,HEIGHT,COLOR) '(an inside-out cube) 'RETURNS THE OBJECTS INDEX You may also consider defining your own objectADDOBJ(TAG$,X[],Y[],Z[],COLOR) 'THE TAG$ IS JUST A STRING WITH NO IMPORTANCE, IT IS SIMPLY TO MAKE IDENTIFYING OBJECTS EASIER 'X[],Y[],Z[] DEFINE EACH TRIANGLE.

Simeon Simeon Scholar Received for knowing a great deal about programming topics Achievements Amazing Page Hidden Achievements Drawing I like to draw! Hobbies It let's you do mass calculations instantly on arrays The calculations are limited to adding, multiplying, subtracting, clamping, multiply&adding, or linear interpolating arrays but if you can build an algorithm with only ARYOP, avoiding loops all together, then that's like infinite power of processing And the only thing making the algorithm slow is the overhead of filling the arrays in the first place And the FOR loop for drawing the triangles :/ That's the SmileBASIC devs giving us the full power of the 3DS in a limited little function 12Me21 12Me21 Admin Syntax Highlighter Received for creating the code syntax highlighter on SBS Night Person I like the quiet night and sleep late.

Programming Strength I noticed the poll about the dlc.

Programming Strength First Day Joined on the very first day of SmileBASIC Source Website If you read the source code the DLC is simply detected automatically and accelerated render functions are used if you have it.

Come to me for help, if you like! Programming Strength First Day Joined on the very first day of SmileBASIC Source Website I'm quite impressed at the efficiency of this engine, moreso that you're still working on optimizing it across all devices. There's a couple things I would change though. Object colors should simply be a single color value, the sort you get from RGB() or the color constants like #WHITE. As it is we can't use either for defining object colors, which makes it quite a bit inconvenient and inconsistent with other graphics functions. If you want you should provide a simple HSV() function that converts the input into RGB and returns an appropriate color code. This does provide an additional calling overhead in some situations when adding objects, I suppose, but I can't imagine you'll be adding lots of objects realtime per frame, and this way is simply more flexible. The same should be done for all functions involving colors. A base scale of 50px per unit is a pretty sane and decent default, but would it be sane to allow the user to change it? What about field of view? Why do you need both an object index and an object mask index? Is the normal index more efficient? Having to deal with two index types is just a bit weird. It might be better in terms of UX but worse in terms of performance to only use one, but OBX[OBJMASK[MY_OBJECT_INDEX]] seems a bit concerning either way as I believe array indexing repeatedly is a performance issue. Simeon Simeon Scholar Received for knowing a great deal about programming topics Achievements Amazing Page Hidden Achievements Drawing I like to draw! Hobbies Yes thanks! I'll do that with the coloring, that'll give a big speed up too And I'll have a scale change variable, sure, I just thought 50 was a good constant FOV is already a modifiable variable Now as for the masking, this is the thing I cannot change, user's won't need to deal with the masking thing almost at all since I'm having functions that do everything for them But the reason is, if you create a bunch of variables and give each one an ID to an object, then deleting the first object will offset every other objects ID Masking runs in O(1) time complexity Deleting any of the items in the array runs in O(1) time complexity also, thanks to 12Me21 So it's nothing to worry about performance-wise Minxrod Minxrod Summer 2016 Contest Participant I participated in the SmileBASIC Source Summer 2016 Contest!
