Irrlicht Engine

Hello, I found that there were references to null pointers in the irrlicht code (using 1.9.0 on openGL ES branch). This is undefined behaviour and it may causes bugs if the cases occur. I think it's pretty minor but just so you know: You can find the offending code snippets bellow:    core::plane3df...

Also, Width = Height?

I already tried to force power of 2 textures but no luck.
And my small textures are not power of 2 anyway, and they don't have issues getting loaded even in 16BIT.

So now I found that for opengl ES 2.0 driver, the crash is occuring in COGLES2Texture::uploadTexture when calling glTexImage2D with the following arguments This is in 16BIT mode (crash) glTexImage2D(3553,0,6408,2301,2308,0,6408,32820,7AE88008) Actually meaning   glTexImage2D(GL_TEXTURE_2D,0,GL_RGBA,...

Actually I got this stack trace on android (didn't retry on windows yet): 01-01 12:55:02.370: I/DEBUG(2159):     #04  pc 00574008  /data/app-lib/com.mylib.mysampleappli-2/libMyLib.so (irr::video::COGLES2Texture::uploadTexture(bool, unsigned int, bool, void*, unsigned int)+1604) 01-01 12:55:02.370: I...

Hello, I got an access violation exception when using irr::video::ETCF_ALWAYS_16_BIT for texture loading from PNG file. Actually it works fine for most of texture, but it crashes when trying to load a big (2301x2308) texture atlas. Below is my helper code for loading a texture. When loading icons i ...

Hello again, I'm keeping on doing more complex rendering on 2 panels, but it feels very buggy. For example, I get issues when adding guienv static text items to display the FPS: The code below won't display the static text on any panel:                 IGUIStaticText* statictext2 = guienv->addStatic...

Finally, there is no explicit API to do it, but we can use a trick of displaying a 2dline to force irrlicht enabling the depth test when it switches back to 3d rendering. Here is the final code in case someone else needs it:                   device->run();                 driver->beginScene(true, t...

Update: I was able to fix the issue by enabling depth test after changing the context:                   device->run();                 driver->beginScene(true, true, video::SColor(0,0,180,255), nativeVideoInfo2);                 glEnable (GL_DEPTH_TEST);                 smgr->setActiveCamera(cam); ...

Thanks for the tip.
Here is what it looks like when PANEL2 displays correctly (as in the code as posted).
PANEL1 and PANEL2 should display the same thing, but they don't!



When looking at the picture, it looks like a Zbuffer issue to me. But it may be something else

Hi all, I am trying to render to two windows panel (using irrlicht 1.8 ), and I don't understand why but it looks like the Z test is failing on the second panel. I am using openGL driver (opengl is required because i want to use irrlicht inside an application that otherwise uses opengl), and I get w...

Hello again, Edit: Nevermind I found it: irdriver->setTransform(irr::video::ETS_WORLD, irr::core::matrix4()); irdriver->setTransform(irr::video::ETS_VIEW, irr::core::matrix4()); irdriver->setTransform(irr::video::ETS_PROJECTION, irr::core::matrix4()); irdriver->setTransform(irr::video::ETS_TEXTURE_0...

Hello Nadro, Edit I was saying that I it worked, and it looked like it at first, but the result is buggy. So I will go with your proposal (using same context for opengl rendering). Thanks. Florian =========== Disregard below comment =============== Thank you for your reply. Actually I was able to ma...

Hello, I am developping a library that needs basically to be able to render something to a few Textures using data from a database, so that the user of the library can then use the textures in OpenGL to draw his application (using the Open GL texture names). I am using Irrlicht because it was easy t...
