lines with gmax

Recommended Posts

Has anyone got lines to work with gmax?I tried the LINES_ material, but it seems as if that's used to build wireframe buildings. I want to make antennas on a building though. I tried to handcode some lines with the new DRAW_LINES, but the lines go completely berserk. I suspect that this feature doesn't work yet...Cheers, Christian

Hi I have tried lines using Scasm commands and they don't work properly, specially at night, as either they become completelly full black or lighted as a candle.....Rafael

That's because the vertices have normal vectors, which is stupid in the first place for lines. I don't know if you can set the normal vectors to 0.0, 0.0, 0.0...I can't get the lines to draw in an ordely fashion at all! The go all over the place. Can you please post a working scasm example (I can translate to bglc myself)?Cheers, Christian

What do you exactly want to draw? I have used the lines_ prefix with success to draw a set of line with the shape of a cone (so they all end in one point). This worked fine. Do you want to draw a single line maybe?Arno

Hi Christian,Phew...I did some test about 2 months agor or so...things are a litle far now in my memory.........by here goes an example.I draw polygons as well using the same line vertex,they are only visisble fron the front, so we can see better what is going on. You will notice that at night you will not see the lines at all, unless when using lightning. I can send you the example macro bgl compiled file if you wish.=================================================set( fsvers 0x800 )Area( C %1 %2 22 )IfVarRange( :lb01 346 %12 4 ) PerspectiveCall( :lb02 ) ShadowCall( :lb02 ):lb01Jump32( :lb99 ):lb02mif( %11 ) RefPoint( 2 :lb03 %4 %1 %2 v1= %10 E= %11 %13 %14 )melse RefPoint( 7 :lb03 %4 %1 %2 v1= %10 %13 %14 )mifendRotatedCall( :lb04 0 0 %5 ):lb03Return:lb04BglVersion( 800 )MaterialList( 0 1.0 0.0 0.0 0.5 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 0.0 0.0 ; 50% transparency 1.0 0.0 0.0 0.5 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 1.0 0.0 0.0 0.5 0.0 ; 50% transparency Night lighted 1.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 0.0 0.0 ; Full opaque 1.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 0.0 0.0 0.0 1.0 1.0 0.0 0.0 1.0 0.0 ; Full opaque Night lighted )VertexList( 0-17 0 0 0.0 0.0 -1.0 0 0 ; #V00000-17 10 0 0.0 0.0 -1.0 0 0 ; #V00001-7 10 0 0.0 0.0 -1.0 0 0 ; #V00002-7 0 0 0.0 0.0 -1.0 0 0 ; #V00003-5 0 0 0.0 0.0 -1.0 0 0 ; #V00004-5 14 0 0.0 0.0 -1.0 0 0 ; #V000055 14 0 0.0 0.0 -1.0 0 0 ; #V000065 0 0 0.0 0.0 -1.0 0 0 ; #V000077 0 0 0.0 0.0 -1.0 0 0 ; #V000087 20 0 0.0 0.0 -1.0 0 0 ; #V0000917 20 0 0.0 0.0 -1.0 0 0 ; #V0001017 0 0 0.0 0.0 -1.0 0 0 ; #V0001120 0 0 0.0 0.0 -1.0 0 0 ; #V0001220 30 0 0.0 0.0 -1.0 0 0 ; #V0001330 30 0 0.0 0.0 -1.0 0 0 ; #V0001430 0 0 0.0 0.0 -1.0 0 0 ; #V00015 )SetMaterial( 0 -1 ) ; 50% transparencyDrawTrilist( 0 2 1 0 3 2 0 )DrawLineList( 0 0 1 1 2 2 3 3 0 )SetMaterial( 1 -1 ) ; 50% transparency lightedDrawTrilist( 0 6 5 4 7 6 4 )DrawLineList( 0 4 5 5 6 6 7 7 4 )SetMaterial( 2 -1 ) ; Full opaqueDrawTrilist( 0 10 9 8 11 10 8 )DrawLineList( 0 8 9 9 10 10 11 11 8 )SetMaterial( 3 -1 ) ; Full opaque lightedDrawTrilist( 0 14 13 12 15 14 12 )DrawLineList( 0 12 13 13 14 14 15 15 12 )EndVersionReturn:lb99EndA===================================Best regards,Rafael>That's because the vertices have normal vectors, which is >stupid in the first place for lines.

Thanks. It looks like your lines are closed. Maybe that's the key, ie maybe it's not possible to just draw one single line?Cheers, Christian

Hi Christian, +----------------+-----------+ 0 1 2The way it works is quite weird and archaic, previous version ways of doing lines was better....As in the design, you have two lines, to draw the lines you have to do:DrawListLines ( 0 0 1 1 2 )It would be wiser to do the full string in one shot, as 0 1 2Yes, you can draw just one line, no problems, as 0 1 in the exampleBestRafael >It looks like your lines are closed.

Weird, I did exactly that (in BGLC that is), but as I said it completely messed things up.I'll have to do some more experiments then...Cheers, Christian
