javascript - How to Detect collision of Cube Mesh with browser boundary in ThreeJS -


enter image description here

enter image description here

i new in 3d games , threejs. shown in image above. mesh @ browser's left boundry , @ time mesh position -1035 instead of 0. means mesh.position.x in threejs not browser window x pixel mesh.position.x in threejs. there calculation convert browser inner width , height same mesh.position.x. how detect collision browser boundary .

three.js uses 3d spatial coordinate system x , z axes horizontal , y axis vertical. origin (0, 0, 0) arbitrary point in space, , can "look around" in 3d world origin might not on screen. coordinates of object in three.js-space also, intents , purposes, arbitrary units.

you can convert between 2d screen space , 3d world space using projectors. going 3d 2d has been answered, , there nice tutorial on topic.

so, find out whether mesh on screen, should project 3d position 2d screen space , check whether outside size of window or canvas.

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]
