nu labi - juus paliekat pie sava es pie sava ;)
dabeigshu savu tooli liidz taadai stadija kaadai gribu tb exporteejas sceena aaraa + kods kas to sceenu ziimee tb dabuujam 3d screenshotu ar visiem meshiem, textuuraam, shaderiem un tad redzees kas un kaa
tad varees arii pa mesham atsleegt un piesleegt un redzees kaa tieshi katrs meshs tiek buuveets/ziimeets/kustinaats

Jaa, dev, kaa tas notiek PI pareizi saprati  bet HL2 man tas uudens iipashi neraustiijaas - diezgan ilgi peetiiju kas un kaa vinjiem, bet vismaz es nepamaniiju
VDL - oho, gribeetu redzeet to tavu tuuli pabeigtu, izklausas pec moshniigas lietinjas...

nu pagaidaam izstaas ceriigi - es praktiski visu izstaas varu paarkjert un pierakstiit - tik vien kaa peec tam plati atspeeleet

yippy
atspeeleeshana daudz maz shancee - probleemas veel ir palikshas ar shaderu atspeeleeshanu bet standarta dx izstaas ka pareizi atspeeleejaas [render to texture moka bik gljuko]

origjinaalais kadrs
3d capture
tas pats 3d kadrs tikai no cita rakursa
kaa redzams kau4kaadas probleemas ar textuuru izpluushanu bet tas buutu praktiski siikums

par hl2 uudeni - nu saaku leenaam nosveerties par labu normal mapeem [veel galiigi neticu bet moka tomeer]
lasiiju par hl2 shaderiem http://www2.ati.com/developer/gdc/D3DTutorial10_Half-Life2_Shading.pdf
samplerRefractSampler: register( s2 );
samplerReflectSampler: register( s4 );
samplerNormalSampler: register( s3 );
samplerNormalizeSampler: register( s6 );
tjipo izmanto vinji normal mapi uudenim [un protams divas textuuras - reflekcijai un refrekcijai]

Nu veciit, tu esi maniaks, un veel maxii ar vissaam textuuraam iedabuuji.
Ar kaadaam speelem sitas darbojas, un kaa tu vispaar extrakto geometriju?
Interesanti buutu kaut kaadu GTA3 pilseetu uzskeerst, apskatiities cik polji sakraameeti, utt. Vai piemeeram Mafiju. |

vajadzeetu darboties uz visiem softiem kas dx9 izmanto [veelaak moka dx8/7/opengl vareetu klaat piemest bet tas nu taa]
gta3 ir map editors - saucaas moomapper http://www.chronetal.co.uk/gta/
ar sho tooli visu pilseetu gluzhi nedabuusi - dabuusi tikai to kas currentajaa freimaa tiek rendereets. tb gribi visu pilseetu braukaa apkaart un peec tam liec kopaa... weee baiss darbs. a ieskatu no taa kaa viss tiek likts kopaa un kaa tiek izmantotas visaadas viltiibas arii no pilseetas daljas var guut.
veel var iesleegt wireframe mode [ieksh hl2 taa diivaini shancee droshi vien deelj shaderu kaudzeem]

Damn, kaapeec es nepamaniiju uzreiz to uudens skriinus pirmajaa lapaa ieliktos? Nevajag updeitot vecos postus, vaig pa jaunam postot taa es nekad neatradiishu taadas interesantas lietas :)

fresnels uz plaknes [refrakcija/reflekcija] |
vari paraadiit shaderi konkreetajam scriinam?
| Quote: | | teixim aatru vilnjoshanos var uztaisiit izmantojot 1d textuuru kuraa ir iekodeetas sin/cos veertiibas un caur sin/cos aatri izreekjinaat normaali - ieguusim smukas sinusoidas kuraam var nedaudz pievienot kaadu random nobiidi lai neizskatiitos tik matemaatiski un shaderis skries paleekdamies |
Vari paraadiit sheideri, kur taa tiek normaalji taa apreekinaati, un tieshaam neizskataas "matemaatiski"?
