Can you put 3d object to a Canvas? If so how do you put a .x object there?

If not:

How do I make the 3d area as only part of my viewable program area? and how do you add 3d objects to that area?

No. You can capture an area using GET IMAGE and then set the image to display on a panel gadget using setPanelImage though.

I don't understand. Can you rephrase that?

Rob, I think you are ahead of yourself, and I think you are leaking inside info about version 2

There's no setPanelImage in the current version

There isn't a canvas gadget in the current version either, so he must be referring to v2.

I am using V2 BatVink.

Thanks RobK checking it out now> No need to rephrase if I can use the panel image.

I am moving 3d objects around the screen and just need to see them in a viewpoint like screen. As the other areas will be displaying data. Can DBpro do this or do I need Blue2 power? I f you can help code in in the following post.

I think I understand now.

Yes it is possible to make 3D appear in the SpaceView gadget, but because GET IMAGE is painfully slow, you can only do it either with a small viewport (200x200 or less), or if you only update the display when it changes - assuming that it only changes when the user does something, rather than continuously.



Otherwise, I would recommend using the SET CAMERA VIEW command. If you want multiple 3D displays which have to be in seperate windows, then you'll need to run more than one exe (with the 3D applications set up with SYNC OFF so that they don't use too much CPU)

I think using SET CAMERA TO IMAGE would be a lot faster.

Isn't it? Wasn't it? Marvellous!

You're correct - but you cannot create a memblock from an image created with SET CAMERA TO IMAGE.

Well I am looking for the best way to do this. I will need speed as there will be a number of 3d objects with some complicated rotations etc. There will be alot of math.
So lets change this:

Should I just make the entire screen my 3d view and put my edit boxes and graphics images over top of it?
-OR-
Or make half my screen with my rest and graphics and the other half with the set camera view?

Not sure if I'm reading this correctly but...

If your'e after multiple 3D windows (All realtime views) then I can't help you. If however, you're after something such as photoshop with a real time 3d window instead of Photoshops bitmap window, then it's entirely possible with Blue 2.

I'm sorry I can't be more specific here (my main blue test code is on the laptop), but essentially here's some (rather vague) guidelines for creating a real time 3d view "Within" a blue 2 application.

1) Create a Blue window without a parent (let's call it 'Blue a').
2) Now create a child window (let's call it 'wind3D') and parent it to 'Blue a'.
3) Grab the 'MS windows' handle of your dbpro window.
And finally...
4) Associate/Attach the dbpro window handle to 'wind3D'

You can find all the information for this procedure by examing the documentation (Be carefull, there are some ommisions/differences between the two types of docs given).

I may also be missing out a neccessary panel procedure here (been some time time since I've tried it and it's a bit vague)

If you want some actual code, I'll be online with the laptop tommorow so I'll give a quick example.

Good Luck.

As I mentioned earlier, you can't make memblocks from camera output images which makes this useless.
