\section Version125 DI-Guy Version 12.5

\subsection v125diguyAPI DI-Guy API

Note that most changes to the DI-Guy API also apply to DI-Guy Scenario.

\subsubsection v1251api Version 12.5.1

• Fixed bug where customer sourced dds files failed to load because we assumed they were lz4'ed.
• Fixed bug where files with capitalized extensions eg "FLT" failed to load.
• Fixed bug where invalid xrefs caused parent bounding boxes to fail to register as possibly valid.
• Fixed hard crash when drawing empty octtree.
• Fixed matrix state glitch when drawing octtree and scene object bounds
• Fixed path planning bug in funnel code when far above the z origin.
• Fixed bug where browsing for a new scene object file name didn't force octtree recreation.
• Fixed logic bug in check visibility code.
• Fixed bug where changing appearances could cause single frame muzzle flashes and loss of character skinning matrices.
• Fixed bug where flt files were unable to have their material edited by the character viewer
• Fixed bug where changing character type caused all action beads to collapse on a path.
• Added additional guide example showing differences between similar and dissimilar character types.
• Fixed bug in built-in OpenGL renderer where fixed function mode didn't properly bind textures. Fixes textureless segmented characters rendering in Motion Editor.
• Fixed joystick not properly loading in I-Guy mode.
• Fixed ray testing against scaled scene objects.
• Fixed off by one error in link combo in character viewer.
• Fixed bug in Lua debugger. "Step over" and "Step out" buttons were not working correctly
• General improvements to code that tests get_enabled() and get_dead() on a character, the code will now also test the character's t_out compared to current time
• Added diguyAgentParams:set_influence_box_enabled() (and get)
• Fixed bug with ground clamping on large scenarios.
• Fixed performance issue with receiving props over the network.
• Improved shadow pass rendering performance.
• Shader cleanup.
• Changed Graphics API shader samples to default point light #define to off.
• Fixed crash when executing gesture that wasn't made for a character.
• Fixed crash when loading degenerate flt file xrefs.
• Improved memory use when decompressing many dds files.
• diguyCharacter::set_orientation() now checks if the character has a vehicle controller and if so, it now allows the caller to hard-set the vehicle's orientation. Previously, only the vehicle controller determined this.
• diguyCharacter::find_path() now checks if the character_type contains the substring 'vehicle' and if so, the path produced will be wide enough to allow the character to pass, based upon character's bounding-box's width.
• Added a number of try/catch blocks to deal with running out of memory while loading extremely large scenarios.
• Added code/UI to allow DI-Guy Scenario to unload textures when not used for a long time. Off by default.
• Added a number of experimental diguyApp memory management functions:

• diguyApp::set_threshold_to_unload_textures()
• diguyApp::get_threshold_to_unload_textures()
• diguyApp::set_texture_unload_frequency()
• diguyApp::get_texture_unload_frequency()

\subsubsection v1250api Version 12.5.0

CRITICAL api changes

• C++ callback:
  

float AltitudeFunction( diguyScenario* scenario, float x, float y, float old_z, int * valid);

• Graphics API

• bdiGraphicsInitGraphicsAPI.use_4x3_shader_matrices must be set to 0 if you aren't planning on upgrading shaders to use 4x3 matrices.
• As a performance optimization we are no longer transposing our internal matrix representation in C++ before sending to OpenGL. 4x4 matrix bind should get updated to

glUniformMatrix4fv(m_bind_location_ufrm_link_matrices, // uniform var location num_mats, // number of matrices !get_transposed_matrix_data(), // whether to transpose matrix mat_data); // pointer to matrix data

• New adaptive guide allowing characters to fix dead reckoning errors with appropriate step and strafe motions. Now the default in the networking system as well as featured in the guide example.
• New texture variation system allowing for infinite variations on next-gen characters. See diguyCharacter::set_use_texture_variations().
• Next-gen characters now have a number of multiple available head appearances.
• Motion engine should now be fully multi-threaded, thread control api is part of diguyApp.
• New C++ documentation system, utilizing doxygen.
• Fixed matrix update issues with motion lod system and skinned characters, motion lod system can be used again with them, same issues had been happening with segmented characters as well. We recommend using multi-threaded pipeline instead of motion lods at this point.
• New ground clamp option 'g' - approximation based on ground clamping vehicle bounds
• Scene objects can now be collada DAEs.
• Added support for bump maps on scene objects.
• New multi-threaded asynchronous texture loader, controllable via scenario UI and diguyCharacter::set_texture_load_behavior() and diguySceneObject::set_texture_load_behavior()
• Collision Infrastructure Improvements:

• Improved performance of ray tests with scenes with many props.
• Scene Object spatial partitioning system has been overhauled allowing scene objects to be repositioned without recreating the octtree.
• Performance improvement for addingdeletingtransforming scene objects.
