thanks ,if you create a lod sphere scene node,tell me!thank you.i think it is a very useful node!

thank you very much,the pics shown on your link seem like effect,can i get access the source code??

Basically, just make a scene node with a sphere mesh a several different resolutions, and then render a different one depending on how far away the camera is. You don't even need to write the code to generate the spheres

yes,your suggestion is a good idea for rendering a sphere,but it ...

does anyone have a sphere scenenode of level of detail, like the world wind's earth,or can somebody give me some advice on this topic?

i want to draw 3d line to a texture, as the example rendering to texture shows, using draw3dline,i can get the correct 3d position.but i can't see the line.can somebody help me?

I think you can definitely handle all of that using irrlicht. Take a look at the tutorials and some of the different camera animators to see how to use the mouse to zoom in and out. You may want to make the distinction between "panning" and "zooming" (panning actually moves closer to the object ...

hello,everyone!now i want to program a 3d home editor,it can create walls,and there are two rulers on the gui,including the top horizontal ruler,and the left ruler,like sweet home 3d's ruler.when you scale or zoom use your mouse the ruler changes with your operation.and grids change too.can somebody ...

thank you very much,i see!thanks again!
