c - What's the 3D structurally simplest file format? -


from computations, i've got lot of raw bytes of data. view them not image, 3d relatively-standard file. (c.f. previous question ppm :what simplest rgb image format? )

i put in file header , bunch of struct point, , open file standard 3d file viewer such g3dviewer.

struct point {     unsigned int x; // coordinates     unsigned int y;     unsigned int z;     unsigned char r; // color     unsigned char g;     unsigned char b; }

i've looked @ .obj file format, forces me translate each point in text line describing cubic vertex.

does simple 3d file format exist ?

the ply format simple.

ply format ascii 1.0 comment object: vertex cloud element vertex 8 property uint x property uint y property uint z property uchar red                   { start of vertex color } property uchar green property uchar blue end_header 0 0 0 255 0 0                         { start of vertex list } 0 0 1 255 0 0 0 1 1 255 0 0 0 1 0 255 0 0 [...]

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
