Hi Stuart You write here it does not work with the crop shader, but does it work with the forest shader? I should have been more exact: The crop shader generates fields within the shader itself, so there is no simple texture file to base the mask on. Object masks still work, but the placement of the objects doesn't match field boundaries, as it does when the shader is disabled. This isn't an issue for the forest shader, as we don't actually use an object-mask for forests as the trees are evenly distributed. -Stuart -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel

I also forgot to mention that I've included a simple algorithm to ensure that objects are placed far enough apart that buildings won't sit on top of each other. Unfortunately it doesn't work for trees or placed static objects, but it does allow you to use much higher densitys of buildings. -Stuart -- Keep Your Developer Skills Current with LearnDevNow!

[Flightgear-devel] Random object/vegetation terrain masking
Hi All, I've just committed to simgear/next and fgdata/master code to allow the placement and rotation of random objects and vegetation to be masked based on a bitmap. So we can now control the placement and rotation of random objects precisely to match the underlying terrain texture. So, for farmland, the farm buildings etc. will appear at the ends of roads rather than in the middle of fields*, and in urban areas random buildings will align with the streets** (which works well with the urban shader IMO). As an extra bonus, I've also added a property (/sim/rendering/vegetation-density) that controls the density of the random vegetation. So you can control how uninviting the forests are based on the abilities of your graphics card :) I've committed changes to materials.xml and materials-dds.xml to make use of this, but there's plenty of room for someone to spend time improving the masking if they wish. The masks are very easy to create: - the Red channel controls Rotation - the Blue channel controls Buildings - the Green channel controls vegetation. (You can also use values 255 on the B and G channel for probability placements) Comments welcome as always. -Stuart * This isn't compatible with the crop shader. I don't know if that is solvable or not. ** There's still a bit of work to be done on the urban masks, as some buildings are intruding onto the highways :) -- Try before you buy = See our experts in action!
