Irrlicht Engine

Great news, many thanks!

That's good news indeed

Hi Sfortza, I believe that Photoshop can transform an image from the usual rectangular projection, to spherical, and you may be able to apply that to the SkyDome. If you look at some of the other pages on that website, you might get some other ideas on how to use it. A SkyBox might be easier to work...

It looks distorted because the Skydome is expecting a spherically mapped image like one of these:

Try using the rectangular version of one of those images.

The texture path for a .obj file should be specified in the .mtl file which usually sits in the same folder as the .obj file. If that doesn't work, check the path to the .mtl specified inside the .obj file. You can open the .obj file in a text editor, but you may need to temporarily rename the exten...

Thanks for the advice. I am actually not working on a game. I just want to create a laser beam on screen and yes I have not worked with irrlicht before and thus asked the question. It would be really helpful if you could just answer my question. Thanks a lot Have you tried going through the tutoria...

Ohh, i tested the code before posting ofcourse, it worked for me... So, i should make a heightmap of 258x258 pixels? That was a stupid mistake : p No, the 257x257 pxel heightmap was right size to use. The terrain it makes has 256x256 facets. You need to space the terrain tiles 256 facet lengths apa...

Have you tried compiling and running Example 12? It already has a Terrain Scene Node. I modified the example to be switchable between the two terrain types: if (iTerrainType == 1){ //Terrain Mesh video::IImage* colorMapImage = driver->createImageFromFile("C:/Program Files/irrlicht-1.7.1/media/t...

When you create your terrain, are you using addTerrainMesh, or addTerrainSceneNode? I believe the TerrainMesh can accept high res height maps (look at iscenemanager.h in the source). THe TerrainSceneNode needs its height map pixel resolutions to be values of 2^N+1 (129x129, or 257x257, or 513x513, e...

doh!
You're right, I left that one out when cutting and pasting.
What a difference a line makes.

I just noticed that the jitterbug patch fixed the erratic motion of the sun, but it caused the moon to dissappear. This was happening because MoonPosition was never being set before being used. To fix this, place the following code before line 124 in IAtmosphereStarSceneNode.cpp, MoonPosition.X = -p...

Hi Cobra,

That did the trick; the sun amd moon no longer do the jitterbug

Thanks a lot posting the fix early, looking forward to 0.1.51

Hi Cobra, I found a minor issue in ICloudSceneNode.cpp at line 661. In the function makeRandomCloud, the color is assigned to the cloud particles in a for loop starting at an index of 1. This leaves the 0th particle with no color assigned, and that particle appears very dark if you’re using directio...

Hi Cobra, Line 448 of ICloudSceneNode.cpp appears to have been commented out by accident. Here are lines 445 through 451: p[1+idx].Pos.X = particle.pos.X + h.X - v.X; p[1+idx].Pos.Y = particle.pos.Y + h.Y - v.Y; p[1+idx].Pos.Z = particle.pos.Z + h.Z - v.Z; //p[1+idx].Color = particle.color; p[1+idx]...

Thanks for the update
I'll be updating my 3d viewer to use this.

One thing I noticed while running the example was that the position of the sun jumps around if the camera controls are enabled and an arrow key is pressed. The same thing happens when the moon is in the field of view.
