Truevision3D Template

[matthew]

I'm really excited about the possibilities of what can be achieved using Truevision3D. ;D

So I've created a Template for your Programmes.

It's rather simplistic at this time but it works.

There are some good Truevision3D Tutorials here.

You'll need to run this first if you haven't already done so.


CONST TV_KEY_ESCAPE = 1 ' The Escape Key on the Keyboard

DIM windowWidth : windowWidth = 640 ' Width of the Window
DIM windowHeight : windowHeight = 480 ' Height of the Window

Graphics.Initialize windowWidth, windowHeight ' Initialise the Graphics

Mouse.Initialize ' Initialise the Mouse if it's needed :)

DIM tv
SET tv = CreateObject("TrueVision3D.TrueVision8") ' Create our 3D Engine  
tv.Init3DWindowedMode System.GethWnd

DIM scene
SET scene = CreateObject("TrueVision3D.Scene8") ' Create our 3D Scene

' ^^
' We need to create an Engine and a Scene before we can display anything on Screen.

DIM inp
SET inp = CreateObject("TrueVision3D.InputEngine8") ' I assume this handles Keyboard Input?

tv.DisplayFPS = FALSE ' Don't display the FramesPerSecond

Do
   tv.Clear ' Clear the Screen
   Scene.Drawtext "Hello World, I'm a Brutus2D-TrueVision3D App!!!", 10, 10 ' Write some Text
   tv.RenderToScreen                 ' Now show our Text on the Screen
System.ProcessMessages ' Keep our Application responsive :)

Loop Until inp.IsKeyPressed(TV_KEY_ESCAPE) ' Loop until the 'Escape' Key is pressed

Set tv = Nothing ' These are Important...
Set scene = Nothing ' They Dispose of everything we've used...
Set inp = Nothing ' So there are no nasty memory leaks.

mouse.terminate ' Terminate the Mouse
graphics.terminate ' Terminate the Graphics

cool... didnt think there was a 3d dll engine

is the collision detection built into the engine?

^^
Yeah, it would appear so.

You should see Guilects' Example if you haven't already.

I've just installed the Truevision3D SDK and I've got it running in C# Express Edition.

Maybe some of the Examples could be ported to Brutus2D?

some notes about Truevision.

I used the old freeware version of the dll.
It has no logo being displayed.

If you use the latest Truevsion dll, alot of the command names have changed and the dll is not backwards compatible.

I was not able to use all of the GET calls, like to get a Vector for teh lens flare effect. I am looking into pointers and memory handling routines.

If you are using the TV keyboard input handler, use the ESCAPE key to exit.

VBScript will not let you assign (what do you call them?) derived classes direclty to one another. The work around is to assign each element of the class to the other classes corresponding element. In the demo I would have liked to do this:

GCamera(1) = GCamera(0)

Instead, I had to do this:

GCamera(1).Ang = GCamera(0).Ang
GCamera(1).X = GCamera(0).X
GCamera(1).Y = GCamera(0).Y
GCamera(1).Z = GCamera(0).Z

I've ran some of the C# Examples and they look really good.

But I think it would be easier to convert the Visual Basic Examples to Brutus2D so I've just Re-Installed Visual Basic Express.

Yes
