Did anyone try cypher ?

I bought Cipher when it first came out for a sub $100 price last year, it has some really amazing "c" programming code and comes with some great tools for creating a 3D project. Cipher would actually be able to be compiled with lcc-win just fine, but it uses it's own layer for dll use. Unfortunately its not a simple dll that you can call functions from it has its own layers and i think this was done to be able to run on any system using a virtual machine. Anyway I don't think Cipher would be a good contender for PB unless you are a "c" programmer, and you can rework the code to fit your needs.

Just recently I had a go at getting TrueVision3d to work in PB (becuase of the COM nature of it), but had problems with the Init command because it expected a form handle for fullscren mode. Have you tried it Codemonger?

funny thing i have tried truevision once in PB ... but i don't think it was successful. I think that was back when PB didn't have good enough support for COM objects, also i think truevision did not have c++ header files available, at that time it was mainly for VB , i think. But truevision would be cool to get working in PB. The form handle should just be the window handle. that's all thats required for fullscreen or windowed mode, maybe you where passing the wrong thing ... If you ever post any code i'll be around to check it out.

Could also do a search online for the open source version of TrueVision (back when it was open sourcE), it's all VB source, but hey.. its out there..

Cheers CodeMonger. The trouble was I had problems because I wanted to keep it secret and couldnt ask anyone for help. I made use aXend's Interface Generator and his COM library also. Here's the code I got up to, believe me its messy (because after trying for ages I just added allsorts in vain attempts to get it working). I dont recommend you run this, but if you do you'll need to use Ctrl+Alt+Del to exit it, then remove all instances of the PB Compiler from the task manager's processes list. Memory leaks all round made me give up hopes of ever getting this to work, until I looked at the "pbidetest2.doc" in my root C dire, which was:

Code: Select all

obj_Engine\Init3DFullscreen(#Temp_Width, #Temp_Height, #Temp_Depth, #Temp_EnableTnL, #Temp_EnableVSync, #TV_DEPTHBUFFER_16BITS, #Temp_Gamma, WindowID) _

This made me think that it was the init routine which was causing the problems, but initializing a window for fullscreen caused problems because I didnt know how to handle it. This file was also in my root C dir, "tv3d_debug.txt":

Code: Select all

Heres the problem : (but their could be more)

Code: Select all

Global OutputID = ScreenOutput()

should be:

Code: Select all

Global OutputID = WindowID()

I believe ScreenOutput was sending a HDC to the variable OutputID ... what you need is the HWND, or windows handle of the window you would like truevision to use for fullscreen. This is the first problem i noticed although their could be others. But give it a shot.

Moonshine · Post by **Moonshine** » Wed Jul 14, 2004 2:14 pm

I think I tried that before but that was the last sourcecode that I saved, I tried to use a pointer to the screen but it didnt work. The windowhandle had no effect if I remember.

Like I said it's mess and I should've read through it before I pasted it...
