Ian Curtis 4a116190b5 When the translator map?? bit is enabled the colour format seems to be 4-5bit. Max observed value is 16. Scaling these values up seems to produce the correct colours in harley and dirt devils. 2017-02-16 17:20:42 +00:00
Ian Curtis 7407d03036 Put a check in there, in case near values come out really close to zero. Fixes a slight corner case in lemans24. A check probably should have been there originally :) 2017-02-08 16:14:50 +00:00
Ian Curtis 24cbeed526 Dynamically calculate near/far frustum planes for each viewport priority layer by clipping the overlapping meshes with the 4 frustum planes. A bit brute forcy, but the results are great. 2017-02-07 14:05:03 +00:00
Ian Curtis 144125a62e mark the nodes without valid distances set 2017-02-05 15:36:05 +00:00

Ian Curtis 72dd0dbf98 only need to cull against 4 clipping planes 2016-12-22 22:09:13 +00:00
Ian Curtis 20a9514aa2 For scroll fog set the viewport to the entire area, allows fog to work in widescreen mode 2016-12-15 19:27:08 +00:00
Ian Curtis ca7046729e properly cache un-normalised texture coordinates, fixes a texturing regression in Daytona 2016-12-15 12:10:52 +00:00
Ian Curtis f355e2d062 fix microtexture colours 2016-12-15 00:45:32 +00:00
Ian Curtis 89e75a9803 Only check scroll fog value from the first viewport from each priority layer. Seems to fix problems with background fogging. 2016-12-14 19:57:05 +00:00
Ian Curtis 707e945db9 delete unused files 2016-12-09 14:15:11 +00:00
Ian Curtis 2c23268d88 Support microtexture relative scale. The exact scaling values are not known, but a 2x difference between each level seems highly likely. We know from visual inspection from scud that the first level is exactly 4. The SDK has a function that accepts a float input for scale and does this. lod = (1/scale) + 0.5. If lod>3 lod = 3. So this is our best guess. 2016-12-09 14:13:46 +00:00
Ian Curtis da8b63b44b The model3 shares vertices between polygons. But it also seems to do this for polygons with different textures. This means the texture coordinate for potentially different sizes textures is shared. Currently this was broken leading to some corrupted looking textures. The fix is to simply cache the old texture coordinates, and recalculate the normalised coordinates in the new texture coordinate space. 2016-12-06 14:39:46 +00:00
Ian Curtis 10a5d2c0e1 refactor 2016-12-06 12:25:34 +00:00

Ian Curtis a310e8e5cf minor optimisations 2016-11-28 17:32:25 +00:00
Ian Curtis abc8c24b69 Only check the geometry for culling with valid node distances. We will need this later. 2016-11-27 19:30:46 +00:00
Ian Curtis fe60d115d2 Revert changes .. if we clip against the real3d clipping planes, our wide screen hack won't work anymore. 2016-11-26 01:19:51 +00:00
Ian Curtis 665fa90425 Get clipping planes directly from the viewport data. Also no need to clip against a far plane 2016-11-26 01:12:08 +00:00
Ian Curtis 54c405709f Need to walk back in memory and check the previous texture tiles to see if they overlap with the current textures being invalidated. If they overlap they must be cleared too. Algorithm is a bit brute forcy and more expensive than I'd like but it fixes the bad textures in Spikeout. 2016-11-22 20:30:10 +00:00
Ian Curtis 84ae8f035c Skip processing the mipmap section of memory. The real3d doesn't create mipmaps down to 1x1 that is needed to do mipmapping properly on modern hardware anyway. 2016-11-21 09:04:56 +00:00
Ian Curtis 2ddc8a30e0 Clear queued texture uploads after processing them. Saves re-uploading the same textures whilst paused 2016-11-20 17:02:59 +00:00
Ian Curtis 10dd530cde More accurate 2D colours. White should map to 255 not 248 2016-11-15 12:44:47 +00:00
Ian Curtis 483ba2f398 Fix the shading in scud. When lighting is disabled the fixed shading intensities appear to be offset values added to the colour value. 2016-11-11 17:50:27 +00:00
Ian Curtis 0a7c0d0864 change throttle logic for smoother playback, we could get closer to 60fps if SDL timers weren't so lame 2016-10-21 00:04:12 +00:00
Ian Curtis 2f49012786 change scroll fog logic to parse the lower priority viewports first 2016-10-09 18:10:57 +00:00
Ian Curtis f0a15febd1 implement scroll fog, fixes a tonne of missing fx 2016-10-09 16:34:12 +00:00
Ian Curtis ef11990d19 Parse out scrollfog value used for blending over the 2d background. 2016-10-08 15:41:16 +00:00
Ian Curtis 33e795de9b Fix scenes with missing fog in ocean hunter. The game was passing negative fog densities. The sign seems to be ignored by the model 3. 2016-10-08 15:15:25 +00:00
Ian Curtis 9eeb81ac69 same fix for legacy engine 2016-10-08 12:10:47 +00:00
Ian Curtis 33cf6c89d1 our scratch mem must match correct max texture size 2016-10-08 11:59:25 +00:00
Ian Curtis c472d90fb9 Fix the sky in advanced stage in Dirt Devils. It uses a massive (for 1998 :p) 1024x256 texture. 2016-10-06 20:10:45 +00:00
Ian Curtis c3581c9fe8 Support multiple microTextures, fixes crazy texturing in sega ski champ. I'm assuming microtextures are always located on the other memory bank to the base texture. This logic seems to work for all our games anyway. 2016-10-06 01:37:29 +00:00

Bart Trzynadlowski 4b184b05dc Updated game loader to make use of latest changes to config tree: generic value types and eliminated pointers 2016-08-24 04:13:23 +00:00
Bart Trzynadlowski c2f80cef6b Support for hex numbers in string to integer conversions (with '0x' prefix) and special keywords in string to bool conversions (true/false/on/off/yes/no) 2016-08-24 04:11:52 +00:00
Bart Trzynadlowski f08ad1584f Added Util::Stricmp() and small tweak to serialization of Util::Format 2016-08-24 04:10:20 +00:00
Bart Trzynadlowski 2efe18b525 Added support for multiple value types in config nodes.
Removed Ptr_t and ConstPtr_t from public interface, moved config tree builders into their own file, and made them pass by reference and value.
Exceptions can be thrown now on lookup failures.
Removed s_empty_node -- failed lookups in [] operator create a permanent "hidden" child.
Updated comment in NewConfig.cpp.
