Using a skydome

[Paul]

Is there any examples of using a skydome, preferably working with framework?

[Rekindled Phoenix]

Within C# and Leadwerks.Net

 

Framework.Effects.SkyBox.Material = new Material("abstract::FullskiesBlueClear0016_2_L.mat");

 

You can also do this easily using the Sandbox editor:

- Drag an Atmosphere object into the world

- Set your desired material file

I thought that required a skybox not a skydome?

[Richard Simpson]

Yeah the editor atmosphere is a skybox. The only way I know how to make a skydome work, would be to model one in a 3d application, then load that mesh in. But i'm not a programmer.

[Rekindled Phoenix]

Richard would be correct. You would have to model a sphere, texture it, and make the object a child of the scene

 

Looking through the Leadwerks Wiki, I found the skybox vert-shader shown here.

 

Creating a Skybox

I used one in the early days of Leadwerks, just placed it in the background world, scaled and textured it and that was pretty much it. Skyboxes seem to exhibit less distortion though. Why the particular interest in a skydome?

Wanted to rotate the night sky to give the effect of the earths movement.

In 3DS MAX have render to sphere map mode.

And there have geo sphere primitive too.

 

So i prefer to make spherical texture, assign it to geosphere fith normals turned to it center.

Load in engine as simple mesh

Create background world, set my sphere there. And render this world before all other scene.

 

Features:

Sky can be turn

Sky can have animated texture

Sky can have another models (like sun, moon, spaceships, or big buildings, or another terrain)

Sphere map much easier to bake from MAX then cubemap

Can be used on very old hardware (samplerCube discarded from shader work)
