Hi there.

I was wondering if anyone knows of a program where you can input details like camera rotation, fov etc. and get a picture with perspective lines set out.

This is possibly bad practice but I would imagine it's useful for learning.

Does anyone know how to do this in 3DSMAX per se?

My way to get a correct perspective is to create a couple boxes in 3dsmax rotate the camera a bit and make a screenshot.

Maybe not the best way but it's my way

[ceenda]

TweeK: Thanks for the reply. Is it possible to get 3DSMax to output a wireframe render to file instead of actually rendering the pic. Do you just use a screen grab or something?

[silber]

not that expert in max but
why you don't try render splines when
you want only the wireframe

to do that put some splines in your scene
go to the modify-panel and make sure that the
,,render splines'' box is checked

hope that will work for you

hmm haven't been using max for while but I think that you can set the material to "wireframe" from the material editor and then just put that material to all the things that you want to be wireframed and then just render.

[BooMSticK]

yes! you can get max to render wireframe outouts.

there are at least 2 ways to do this..

1) force wireframe rendering which will render all objects as wireframes. Just hit the tab in the 'render scene' dialog box
2) Assign a wireframe material to your object(s). In the material editor you will find a little checkbox saying 'wire'. Check that and you are all set.

hope this helps you out.

Thanks everyone!

Hey Ceenda, nice 3D engine, heh I just saw it on Flipcode...

Freehand 9 has a tool for making perspective grids. I haven't actually tried it yet though, so I can't say if it's any good - still, you might want to check it out.

looks really great ceenda!
especially the last screenshot.

may I toss some questions at you?

* Did you make the engine from scratch or from some already existing code that you modified/used?

* Can something like this be made in Visual Basic / in Java?

Thanks..
As you clearly see I am far behind and not up to date when it comes to programming stuff.

Nex: sure.

* What language did you program the engine in?

The engines were programmed in vanilla C/C++. By this I mean that there's a lot of C++ in there but the program is not entirely class based.

* Did you make the engine from scratch or from some already existing code that you modified/used?

Well, OpenGL handles things like drawing textured polygons but the code for setting up the landscape and importing the textures was my own code and I tend to write these things from scratch. With regard to the LOD program I had to read a paper on the subject to get an idea of the algorithm behind it.

* Can something like this be made in Visual Basic / in Java?

Well, probably not Visual Basic but I used to know a guy who wrote a Java library called GL4Java which was an OpenGL library that ran programs / games in your browser window. He even used one of my early landscape engines to promote GL4Java.

If you want to have a look at my code it is available to download.

I'm not really known as a geek because I'd still rather go to the pub than program... however, I've been known to turn down a night out in favour of my Wacom. There's probably a bit of geek in all of us.

[Nex]

whow that was quick! thanks!

One last question:
There are some free c++ compilers out there.. did you try/can you recommend any of them?

[ceenda]

He he, I only posted the pics 5 mins ago.

DJGPP (www.delorie.com) is quite highly respected as a free compiler. Apparently, the original Quake was written using DJGPP.

If you are a student then Microsoft will actually sell you a student license. I have the latest version of Visual C++ and I continue to get the latest versions until my license runs out. I only paid about 100 quid for a student license.

okeydoke! thx

Hey Ceenda, I was wondering, I have a projet I was working on, which will most likely require a Tile based 3D engine with collision and line of sight comperable to something in X-com or Jagged alliance ? for a tactical futuristic wargame (turn/real time based, my own gameplay design) do you do pro bono work? my current programmer is working on an Isometric prototype to test the gameplay, but he's never done much graphics before and works in Delphi.... think you could help me out? can you contact me through ICQ: 7001326 or AIM: Shahar2k

I think psi burn was talking about wanting to make a program like this, here is the thread:

He he, blatant plug time. Thanks for setting that up shahar2k.

Danny - why is using a plugin for perspective any worse than using a ruler?
