You did not set Normal ...this may be ok if you disabled lighting but if lighting is on you might get weird results. I'm working on it! :) I'm trying to make a sun ... I've calculated positions and it's work just fine ... now the normals should be the vector: (sunpos - cam_pos).normalized(); I thin...

Now I know
Anyway ... if you read my first post you will se that I setted most things ... the only problem was this: Thank you again!

new code: m_tex[0].Pos = vector3df( m_pos.X-0.5f, m_pos.Y+0.5f, m_pos.Z ); m_tex[1].Pos = vector3df( m_pos.X-0.5f, m_pos.Y-0.5f, m_pos.Z ); m_tex[2].Pos = vector3df( m_pos.X+0.5f, m_pos.Y-0.5f, m_pos.Z ); m_tex[3].Pos = vector3df( m_pos.X+0.5f, m_pos.Y+0.5f, m_pos.Z ); m_tex[0].TCoords = vector2df( ...

1) texture is not NULL: 2) Loaded texture: home/radu/Proiecte/3D_data/Example1/textures/sun/sun.png 3) Vertex data is calculated dinamically ... the uv coords ... hm ... which parameter contains these? 4) are the code snippets exactly the same as you use in your prog ??? then there is an error with ...

here is the code: SMaterial material; material.Lighting = false; material.ZBuffer = true; material.ZWriteEnable = true; material.BackfaceCulling = false; material.TextureLayer[0].TextureWrap = video::ETC_CLAMP; material.setTexture( 0, texture ); here is the draw: videoDriver->setMaterial( m_material...

Yupiiiiiiiiiiiiiiiii! I did it! :) Here is the code: char szFile[1024]; sprintf( szFile, "%s%s", workingDir(), "objetcs/latura_podea.3ds" ); scene::IAnimatedMesh* m1 = sceneManager->getMesh( szFile ); IMeshManipulator* meshMan = sceneManager->getMeshManipulator(); int nIndex; for...

Fixed the screen depth set to 32 bits and it's working! Thank you!

I have a problem with textures ... here is my code: driver->setTextureCreationFlag( video::ETCF_CREATE_MIP_MAPS, false ); smgr->addSkyBoxSceneNode( driver->getTexture( m_szSkyBox[0] ), driver->getTexture( m_szSkyBox[1] ), driver->getTexture( m_szSkyBox[2] ), driver->getTexture( m_szSkyBox[3] ), driv...

Hello I'm trying to scale a mesh and nothing happens. Here is the code: sprintf( szFile, "%s%s", instance()->dir(), "objetcs/cub_4_laturi.3ds" ); scene::IAnimatedMesh* m = instance()->irrSceneManager()->getMesh( szFile ); IMeshManipulator* meshMan = instance()->irrSceneManager()-...

Another posibility is to create a ByteArray class and implement methods like WriteByte, WriteInt, WriteFloat, WriteString, etc and ReadByte, ReadInt, ReadFloat, ReadString. And then a SaveManager class who has a ByteArray prroperty and saves/loads to/from a file anything you want. It's tricky, but a...

I see! And what should I do if I want to draw an image in a rectangle for example: 1) tex is 50x50 pixels 2) rectangle is 100x100 pixels 3) I want the texture to be drawn having 100x100 pixels. I've tried that with that function and I saw nothing but my texture drawn having 50x50 pixels and the rest...

I saw the code in function: void COpenGLDriver::draw2DImage(const video::ITexture* texture, const core::position2d<s32>& pos, const core::rect<s32>& sourceRect, const core::rect<s32>* clipRect, SColor color, bool useAlphaChannelOfTexture) And there are some lines of code: glTexCoord2f(tcoord...

Now I have another "problem". How can I draw that texture in 3D space (not 2D, using IVideoDriver->draw2DImage( ... );
I want to draw it in an 3d quadrilateral.

//later
And of course scale, rotate.

Thank you very much! :) I new about IImage* IVideoDevice::createImageFromData(ECOLOR_FORMAT format, const core::dimension2d<s32>& size, void *data,...); And I thaught that ITexture * IVideoDevice::addTexture(const c8* name, IImage* image); will load a texture from a file ... I should look at the...

I have an image in memory, I mean I know width, height, type (eg. ECF_A8R8G8B8) and a pointer to bytes data. How can I create a ITexture on the fly? (without write a png file to the disk and then driver->getTexture( "my_file" ) - I cand do that but it's not quite a cool option). Thank you!
