nenoslogos, ja izmantos virziengaismas! pag pamekleeshu labus efektus...
taa fiksi rendermonkey'aa veidojot - bumpmappings terrainam!
buutu forshi, ja buutu lietotas dinamiskaas gaismas..

Neredzu tur nekādu bumpmappingu. Redzu tikai lightmappingu (vai arī parasto N.L apgaismojumu).
programmer: lietojot alfa-blendigu (aka "caurspīdīgumu") ir jāatcerās, ka tas ir jūtīgs pret poligonu zīmēšanas kārtību. "Caurspīdīgums" nestrādās, ja zīmēsi tālākos poligonus pirms tuvākajiem. Ar to ir diezgan daudz jāuzmanās. Tavā lietā es lietotu multitexturingu un tekstūru kombaineri (GL_ARB_texture_env_combine). Vai arī, ja tev pavecākas videokartes nav svarīgas, tad ARB/GLSL šeideri. |

papildinaashu: ja divi tuvi poligoni buus ziimeeti taalu no kameras, tad var veidoties z-fightings, kuru var mieriigi apiet ar depth funkcijaam!

| Pret z-fightingu jācīnās ar projekcijas matricas mainīšanu vai depth bias, nevis depth funkciju mainīšanu. Tās mainot modernās videokartēs būs pamatīgs performance-penalty. |

nu es domaaju izmantot (ja taads eksistee) kautko liidziigu dx'a slope scale depth bias kaa sheit: http://www.codesampler.com/dx9src/dx9src_5.htm#dx9_depth_bias
baigi labs!

| Tad tā uzreiz vajag arī teikt - depth bias, nevis depth funkcijas |

nuu jaa, vnk biju domaajis depth kontroles funkcijas.. tas ko tu te paraadiiji, man liekas, ka ir domaats stencila darbiibaam arii... btw par taam runaajot - ir iespeeja arii ar stencilu sakaartot pareizi visus objektus taa, lai ziimeejas pareizi!

Nē, tās ir arī depth funkcijas. Izlasi uzmanīgāk: | Quote: | | The values in this enumerated type define the supported compare functions for the D3DRS_ZFUNC, D3DRS_ALPHAFUNC, and D3DRS_STENCILFUNC render states. |
| Quote: | D3DRS_ZFUNC
One member of the D3DCMPFUNC enumerated type. The default value is D3DCMP_LESSEQUAL. This member enables an application to accept or reject a pixel, based on its distance from the camera.
The depth value of the pixel is compared with the depth-buffer value. If the depth value of the pixel passes the comparison function, the pixel is written.
The depth value is written to the depth buffer only if the render state is TRUE. |
