Irrlicht Engine

Hey hey,

I have a project with a collision system setup like this:

CNodeA derived from ISceneNode
|
> unknown number of children of CNodeB derived from ISceneNode with IMetaTriangleSelector
|
> this IMetaTriangleSelector contains a number of CSelector derived from ITriangleSelector that is ...

Hi alc!
I'm not sure about getPitch, sounds like it would fit there.
You can't modify the pixels of a rendertargettexture. It is in fact a copy of the texture like you suggest. I don't think there's an easy fix for this, since a rendertarget is pretty different from a regular texture.

Thanks for ...

Hi Eagle!
The Irrlicht object will hopefully be released the same time as this Mesh object, not long after MMF2 is released. Thanks for the interest.

can't you just tell us what exactly you want to do? or is that a secret? Not exactly a secret. I'll try to be as precise as possible.
There's a product called Multimedia Fusion created by ClickTeam . Simply put it is a program for creating other applications (games/mediaplayers etc). the second ...

There is not much room for improvement, if you render each mesh seperately. Question is: Do you really need to?
That's a good question. The problem is; as the project is a plugin there may be lots of different mesh-objects with different sizes and configurations. I'll try to elaborate on your ...

Thanks for the interest, Baal.
Ok this is what I'm doing:

Begin scene
Set rendertarget
A single mesh is drawn
End scene
Lock rendertarget
Load rendertarget to destination surface

This is then repeated for every mesh used by the application.
As reference I use the sydney mesh supplied with ...

Hey everyone!
I'm making a plugin/extension to a multimedia creation application using Irrlicht. My plugin renders a single mesh without any fancy stuff like shaders/shadows, this procedure will then be repeated an arbitrary number of times every frame, depending on how many copies of the plugin ...

i dont think you can lock a render target (yet). you can however grab screen data using either directx or opengl. see here for opengl.
Emil Halim's Magic2d library can record to divx avi, I assume this is using directx and vfw or something
I posted a fix to locking d3d8/d3d9 rendertarget textures ...

heh thanks

Here's my fix for locking d3d8/9 rendertargets

Here's the url to my fix for that in 0.14

Hi everyone!
This is how to modify the engine (0.14.0) so that you can use ITexture::lock() on textures created with IVideoDriver::createRenderTargetTexture().

Direct3D9
CD3D9Texture.h <-- URL to updated file

In the class definition, add a protected IDirect3DSurface9 member

IImage* Image ...

Thanks for that Nico. Looking forward to what you'll find out!

Update:
I've been able to lock the texture when using OpenGL, but not with directx 8 or 9. The weird thing with OpenGL is that when I use draw2DImage to draw the texture afterwards, it is flipped vertically. Also the colors returned by getPixel is wrong or different than expected.

Hi all!
Is it possible to lock an ITexture created with IVideoDriver::createRenderTargetTexture? Everytime I try to lock such a texture it returns NULL. Normal textures work fine.

Thanks
