Irrlicht Engine

Looks wonderful! Can't wait to see the code.

"Open source" means nothing without a license. You need to specify how people are allowed to use your source. Like, can I put this in a commercial project? Do I need to share the source of my project if I use this? Legally, nobody can do anything with your code unless you license it.

These might be ...

There have been some interesting threads about modeling planet surfaces. Unfortunately I didn't bookmark them... search should turn them up.

If scientific accuracy isn't one of your goals, I wouldn't even bother with Newtonian physics. Make the orbits circular and be done with it.

The part that ...

For #2, google 'opengl framebuffer'.

Also, something you might not be aware of is that an X server runs on a client machine, and an X client runs on the server machine. It seems backwards, but the "service" an X server provides is drawing on a screen. Your Irrlicht app is an X client. Maybe you ...

I would look up the feature list for that driver and see if it supports GLSL at all.

@freetimecoder: That first snippet you posted looks like what I want to do. But I don't know where that code would go. Did you create your own scene node type and put that in the render() method?

I'm interested in this as well. Are there actually any alternatives to multipass rendering, other than using custom shaders?

My understanding of EMT_SOLID_2_LAYER is that the base texture is always rendered at 100% alpha, and then the second texture is blended over it based on the vertex alpha. So ...

Is the method arras describes here the only way to blend more than two textures without using custom shaders?

While we're on the subject, I'm not entirely sure blending multiple textures is the best solution to my problem. I'm working ...

To blend more than two textures, do I need to do something like what arras describes here?

BTW, the docs say that EMT_SOLID_2_LAYER isn't implemented for OpenGL, but that's what I'm using.

[complete edit]

Turns out it is, in fact, working more or less how I expected. I just didn't expect it to blend all the way across the poly. The two textures I was using had very different amounts of contrast, so the blending was difficult to see. It's more clear with different textures:

Awesome, thanks.

Say this code is in a function:


core::vector3df v0 = core::vector3df(-1, 1, -1);
// other vectors
SMeshBuffer* buffer = new SMeshBuffer();
buffer->Vertices.push_back(video::S3DVertex(v0, n0, clr, t0));
// other vertices
SMesh* mesh = new SMesh;
mesh->addMeshBuffer(buffer);
// blah blah
return ...

Isn't there some way to set up a material so that it has multiple layers of textures, and then vary how they're blended in each triangle by changing the alpha component of the vertex colors? I'm not interested in exactly how to do that yet... just whether something like that can be done.

I just finished my first trivial Irrlicht demo: a fully UV-mapped and textured cube. Thanks to all who answered my noob questions! I'm a long way from writing a game (actually, my goal is just a UI mockup for a game) but I'm having fun learning stuff.

My next step will be writing functions to ...
