Added functionality:
- New class renderablesphericalgrid is repurposed code from powerscaledsphere class.
Due to z-buffer issues used as reference grid to confirm planetary orbits are correct.
This has been a major problem as prior we had no visual reference.
Now we have a Galactic-, Celestial- and Ecliptic-coordinate grid.
To this also added separate shader: grid_vs.glsl / grid_fs.glsl
These grids have a static-rotational matrix derived from partiview (thanks to Brian)
since spice req. to-from frame to compute rotational matrix.
Time dependency:
- Added struct RuntimeData - which for now only contains openspace time and is passed to all renderables
- All renderables accept runtimeData, keep private reference and use for computation of rotational matrix
- This obviously carries corresponding changes to Scenegraph and ScenegraphNode.
Spicemanager:
- Added function that more easily provides access to rotational matrix used in spice
(used in renderableplanet for computing planetary objects spin around axis)
Ephemeris-classes:
- Now compute ephemeris from spice based on timeepoch in runtimedata
TODO: once z-buffer fixed - set ephemeris correctly as meters (not kilometers)
Renderengine:
- Advances time with the advanceTime method in RuntimeData struct
ISSUES:
- Our Y axis NOT same as SPICE or star-catalogue, all renderables rotated now 90deg, needs redefinition,
lots of debugging and major headaches before this conclusion.
- Depth buffer needs to be fixed in order to properly place planets.
- Spice kernels have finite time-range, when time stops - simulation ends - ugly fix: reset time to zero.
Possible fix: kernels de431 (part 1-2) cover huge timespan and most likely have functions to extrapolate time,
drawback is that they are 1,7 gb each.
TODO:
- Compute and draw dynamic ephemeries for each renderable. Either do full year sweep then update for each point or
create a tail of linesegments for each planet. Dont know yet how to do this, would like spicephemeris to be
sub-class of Renderable (have own render() method) - good/bad?
- Global shader settings can now be added.
- ShaderCreator builds the shader and stores a generated shader file
with all included source.
- Small TransferFunction bugfix
- Pointing to bugfixed Ghoul
- Pointing to Ghoul with Linux file callback
- Fixed interaction distance control bug when moving to close
- Distance control with mouse wheel added
- Kameleonwrapper normalization based on histogram
- ABuffer seems to work with small issues
Renamed OpenCL qualifiers due to conflict with "ERROR" macros
Removed boost::timer and boost::system dependencies
Added fixed for Windows path handling
- Added hack in VolumeRaycasteBox for SGCT Left/Right clearing
- Fixed quad dimensions to depend on viewport size
- Updated RenderableVolumeExpert to render correctly
- Small changes to SceneGraph to make it easier to switch between volume
rendering and Earth
- Added new volumeraycaster classes
- Fixed many small warnings in OpenSpace
- Linked to updated Ghoul and Openspace-data
- TODO cleanup in volumeraycaster classes
- TODO Add an advanced volumeraycaster class to use during development
- BASE_PATH is set using the openspace.cfg file. The binary will look
upwards in the directory hierarchy until it is found.
- All other paths is defined in the configurationfile. Paths may be
absolute or relative using the ${BASE_PATH} token
- Moved SGCT configuration files to its own folder
- Updated tests to support new configuration loading
- TODO: Make the loading of configuration easier for the programmer.
- Made the BASE_PATH variable relative to the binary, correctly set
using the CMake provided path to the project folder
- Fixed SceneGraphNode tests using std::string and Dictionary creation
using intermediate Dictionaries.
- Moved all OpenSpace headers to separate include directory
- Added OpenSpaceTests binary with OPENSPACE_HAVE_TESTS define
- Added CMake setting of BASE_DIR
- Added OpenSpace initial tests for SceneGraph and SceneGraphNodes
- Added OpenSpace initial tests for psc and pss
- Restructured OpenSpace so no GL functions are called in constructors
to make the classes testable
- Todo: Make the base dir possible to set through command line argument
and configuration file
