* Create a RenderableNodeLine example asset * First version of node direction hint renderable (arrow) * Add possibility to set length as a multiplier of the bounding sphere * Draw arrow cylinder using index array * Update exponents and min max values for lengths * Draw arrow head * Only update arrow geometry when positions change * Add some properties to control visuals of arrow * Implement invert option * Add normals and shading * Set arrow head size by length percentage instead of angle * Add bottom circle to cone * Cleanup and update examples * Remove non-existing property from example asset * Fix vertices not updating if anchor node was changed And some missing updates on property change * Start cleaning up some shape rendering helper functions * Cleanup code and move cylinder function to helper class * Refactor cylinder creation code (fewer loops over same vector) * Update transformations to correctly scale and place arrow * Add the cone to make the arrowhead * Update faulty triangle normals * Add property visibilities * Rename NodeDirectionHint to NodeArrow * Apply suggestions from code review Co-authored-by: Alexander Bock <alexander.bock@liu.se> --------- Co-authored-by: Alexander Bock <alexander.bock@liu.se>
