Irrlicht Engine

i made a raycast version. polygon cubes for voxel feels like cheating.
this is probably how voxatron does it anyway. but with better quality :)

runs on android at just 5fps. but at least the frame rate is constant - no hiccups

one problem with raycast is no easy way to handle floating objects as ...

15FPS on Android

there is a hiccup though when i scroll through the map - that is when many chunks of voxels are processed.
i could cache the entire map for speed but that i'd have to make it very efficient on memory

the choppy video was just from the recording.

i did a round of optimization and got the polygon count down and framerate further up.
this runs on Android by the way. but still at just around 15 fps.

Hi,

irrlicht can do voxatron-like game :)
view area is 128x128x64 voxels
fps is around ~60 with around ~30K tris on OpenGL driver. faster with D3D9.

still needs better lighting - shadows
maybe occlusion culling too

Hey m4rvin,
I assume it has something to do with losing the opengl surface. Did you run into this problem?.

yes, this has got to do with losing the opengl surface.. and as a result, losing all loaded textures. the irrlicht port didn't reload the texture automatically.

i simply reloaded all the ...

yup, it's not meant to be complete. but it can be plugged in easily.

here's the code with a demo program.

sprites ...

this is my own implementation of a 2d sprite batch. ie draws a whole batch of sprites in one go. quite need for mobile games.

each sprite can do the basic transforms. rotate, scale, color with alpha

it works with IVideoDrivers implementing draw2DVertexPrimitiveList

590 tris @ 40 fps on the ...

i think i did.
sooooo... you don't know?

i was able to compile both, with ...

hi,

i finally finished something using irrlicht engine

it's 2d android game
solitaire (70 game types) -- i ported my old solitaire code from the pocket pc (c++)

i stripped out most of the engine features to make it lite. and added a SpriteBatch manager for faster 2d ...

4 corners (vtx[]) ... GL_QUAD?

isn't there a DX_QUAD?

you're spending too much time with birds

please count

S3DVertex vtx[4];
vtx[0] = S3DVertex((f32)poss.UpperLeftCorner.X, (f32)poss.UpperLeftCorner.Y, 0.0f,
0.0f, 0.0f, 0.0f, color,
tcoords.UpperLeftCorner.X, tcoords.UpperLeftCorner.Y);
vtx[1] = S3DVertex((f32)poss.LowerRightCorner.X, (f32)poss.UpperLeftCorner.Y, 0.0f,
0.0f, 0.0f, 0 ...

whats is more complex with passing a QUAD and passing a RECT?

yes, i agree that there are better ways of achieving rotation & scaling, skewing and etc

but for implementation purposes of draw2dImage ... wouldn't it be sensible to pass an actual quad with four corners than a rect? the implementation uses GL_QUADS after all.
