Let's pretend I prefer to spell 0 grey the right way. :) I can define a new name for "Grey". 0 Now I can use either Grey or Gray without worrying. 0 COLORNAME Grey 7 0 0 I define the main colors of my model here, 0 so it is easy to try out new colors. 0 COLORNAME accent_color Grey 0 COLORNAME main_color Black 0 0 Let's redefine Blue to use black edges 0 The syntax of a color definition is: 0 0 COLOR index name edge_color r g b alpha d_r d_g d_b d_alpha 0 The index is an index into the color palette. Ldlite allows 0 you to use the numbers 0 to 255. By default, the numbers 0 from 0 to 64 are defined to match LDRAW's, the rest are 0 currently undefined. 0 LDRAW used the numbers from 256 to 511 to represent dithered 0 combinations of the first 16 palette entries. You can still 0 use the numbers from 256 to 511 in your models, but to make 0 life easier, LDLITE allows you to set palette entries to 0 dithered combinations directly. The COLOR command expects 0 two sets of rgb values which it will dither. 0 For solid colors, set both r,g,b,a and d_r,d_g,d_b,d_a to the 0 same values and no dithering will occur. 0 Alpha should be 255 (or 0xff) for opaque colors. 0 For transparent colors, set d_alpha (i.e. on the dithered color) to 0. 0 If you set alpha to zero on both colors, nothing will be drawn at all. 0 I'm re-using the default r,g,b values for blue, which can be 0 found in the ldlite source file "stub.c" near the top. 0 COLOR 1 Blue 0 0x00 0x33 0xb2 0xff 0x00 0x33 0xb2 0xff 0 0 COLOR 1 Blue 0 255 153 0 0 255 153 0 255 0 0 Actually, I've changed my mind. The standard color "Black" in 0 palette index 0 is sort of a really dark grey. I want the 0 edges on blue to be pure black, so I'll use the new "immediate" 0 form of a color, which is seven hexadecimal digits. 0 The first digit is a 4 for opaque colors, or 6 for transparents. 0 The next three digits are the red, green, and blue values 0 ranging from 0 to f. The last three digits are for a 0 dithered color. If you want a solid color, just use the 0 same values you used for the first three digits. Since I 0 want a pure black, the color will be 0x4000000. (I could also 0 use the decimal number 117440512 if I wanted.) 0 Note that the immediate rgb colors have only 1/16th the possible 0 values a palette entry has. If you need precise colors, 0 redefine an unused palette entry. 0 COLOR 1 Blue 0x4000000 0x00 0x33 0xb2 0xff 0x00 0x33 0xb2 0xff 0 0 One trick I use in testing models is to make some parts invisible. 0 Here I set a pair of colors to be inverses of each other, to 0 make sure no edges get drawn. 0 COLOR 255 Invisible 254 0 0 0 0 0 0 0 0 0 COLOR 254 Invisible-Edge 255 0 0 0 0 0 0 0 0 0 0 In LDLITE, you can define points for later use. Here, I define 0 a shorthand for the z axis, so that my later use of 0 the ROTATE command is easier to read. 0 POINT z_axis 0 0 1 0 0 I find transform matricies to be tedious. So I 0 define some shortcut names for the ones I use. 0 MATRIX m_default 1 0 0 0 1 0 0 0 1 0 MATRIX m_rotate90y 0 0 -1 0 1 0 1 0 0 0 MATRIX m_rotaten90z 0 -1 0 1 0 0 0 0 1 0 MATRIX m_rotaten90y 0 0 1 0 1 0 -1 0 0 0 The following transforms are not physically possible, 0 and I should find an equivalent, physical one. 0 MATRIX m_flipz 1 0 0 0 1 0 0 0 -1 0 MATRIX m_flipxz -1 0 0 0 1 0 0 0 -1 0 MATRIX m_swapxz 0 0 1 0 1 0 1 0 0 0 0 Now I being defining my model. 0 landing skids 1 accent_color -60 -8 -90 m_default 3023.dat 1 accent_color -60 -8 90 m_default 3023.dat 1 main_color 80 -8 -50 m_default 3023.dat 1 main_color 80 -8 50 m_default 3023.dat 1 accent_color 90 -32 50 m_rotate90y 4287.dat 1 accent_color 90 -32 -50 m_rotate90y 4287.dat 1 main_color 70 -32 50 m_flipz 3665.dat 1 main_color 70 -32 -50 m_default 3665.dat 0 STEP 0 rear stealth engines 1 main_color -30 -32 -80 m_swapxz 4856.dat 1 36 -70 -24 -70 m_default 4073.dat 1 36 -70 -24 -90 m_default 4073.dat 1 36 -70 -32 -70 m_default 4073.dat 1 36 -70 -32 -90 m_default 4073.dat 1 main_color -30 -32 80 m_swapxz 4856.dat 1 36 -70 -24 70 m_default 4073.dat 1 36 -70 -24 90 m_default 4073.dat 1 36 -70 -32 70 m_default 4073.dat 1 36 -70 -32 90 m_default 4073.dat 0 STEP 0 floating bricks 1 main_color -40 -16 0 m_swapxz 3020.dat 1 main_color 50 -32 0 m_swapxz 3666.dat 0 STEP 0 unitron docking mount 1 Blue -50 -40 -30 m_swapxz 3040.dat 1 Blue -50 -40 30 m_swapxz 3040.dat 1 accent_color -50 -40 0 m_swapxz 3700.dat 1 Blue -30 -40 0 m_swapxz 3010.dat 0 STEP 0 wing surfaces 1 main_color -70 -40 80 m_swapxz 3710.dat 1 main_color -70 -40 -80 m_swapxz 3710.dat 1 main_color 80 -40 80 m_rotate90y 3933.dat 1 main_color 80 -40 -80 m_rotate90y 3934.dat 1 accent_color -20 -40 -120 m_default 3936.dat 1 accent_color -20 -40 120 m_flipxz 3935.dat 1 main_color 40 -40 0 m_swapxz 3020.dat 1 main_color -70 -48 80 m_swapxz 2419.dat 1 main_color -70 -48 -80 m_swapxz 2419.dat 0 STEP 0 shield generators 1 Trans-Light-Green -50 -56 130 m_default 4073.dat 1 Trans-Light-Green -50 -56 -130 m_default 4073.dat 1 Trans-Blue -50 -64 130 m_default 4740.dat 1 Trans-Blue -50 -64 -130 m_default 4740.dat 1 Trans-Light-Green -50 -72 130 m_default 4073.dat 1 Trans-Light-Green -50 -72 -130 m_default 4073.dat 0 STEP 0 cockpit 1 main_color 0 -48 0 m_default 4212.dat 1 accent_color -50 -48 0 m_swapxz 3023.dat 0 STEP 0 engine intake 1 accent_color 30 -64 -70 m_rotate90y 4286.dat 1 accent_color 10 -56 -70 m_default 3024.dat 1 main_color 10 -64 -70 m_default 3024.dat 1 Blue 20 -72 -70 m_default 2412.dat 1 accent_color 30 -64 70 m_rotate90y 4286.dat 1 accent_color 10 -56 70 m_default 3024.dat 1 main_color 10 -64 70 m_default 3024.dat 1 Blue 20 -72 70 m_default 2412.dat 0 STEP 0 This next assembly is several stacks of 1x1 round plates 0 turned sideways and stuck onto a 1x2-1x4 bracket. 0 I make extensive use of the TRANSLATE and ROTATE 0 commands. 0 There are also SCALE and TRANSFORM commands.
