@"With Ab3d.PowerToys library it is possible to show 3D lines (this is not possible when only WPF 3D is used). But the problem is that the geometry for 3D lines (2 triangles for each line) need to be generated on the CPU. Because 3D lines need to face the camera, the geometry needs to be regenerated on each camera change. This can slow the performance of the application when a lot of 3D lines need to be shown.
The Ab3d.PowerToys library can also generate edge lines based on the angle between triangles (if angle is bigger then the specified angle, then an edge line is created).";
DXEngineFeaturesInfoControl.InfoText =
@"Ab3d.DXEngine can use hardware acceleration to create the geometry for 3D lines in the geometry shader. This can render millions on 3D lines on a modern GPU.
What is more, as shown in this sample, the following additional features are available when using Ab3d.DXEngine:
1) It is possible to set line depth bias that moves the lines closer to the camera so that they are rendered on top of the 3D shape. This way the lines are not partially occluded by the 3D shape because they occupy the same 3D space. The depth bias processing is done in the vertex shader.
2) It is possible to render object's outlines. Here a technique is used that first renders the scene with black color and with expanded geometry. Then the scene is rendered normally on top of the black scene. For other techniques to render object outlines see the 'Object outlines rendering' sample.
3) To reduce anti-aliasing the WPF 3D can use multi-sampling (MSAA). With Ab3d.DXEngine it is possible to further reduce the aliasing and produce super-smooth 3D lines with using super-sampling (SSAA). This renders the scene to a higher resolution (4 times higher when 4xSSAA is used). Then the rendered image is down-sampled to the final resolution with using a smart filter. This can be combined with multi-sampling to produce much better results that using multi-sampling alone.";

@"A new RenderObjectsRenderingStep is created that renders all objects with SolidColorEffect with black color. The SolidColorEffect has the OutlineThickness property set and this expands the object's geometry in the direction of triangle normals (this is done in vertex shader). Then the scene is rendered again with standard effects on top of the black expanded scene.
To render outline around each object uncheck the 'Outline CullNone' and 'WriteMaxDepthValue' CheckBoxes. But on simpler objects with less triangles this may not render outlines in all directions.
To render silhouette around the whole 3D scene and not around each object, then check the 'Outline CullNone' and 'WriteMaxDepthValue' CheckBoxes. The first CheckBox will render back and front triangles. The second will render the objects to the back of the 3D scene (after all other objects).
This technique works well on objects that have a lot of smooth shaded positions and do not have sharp edges with big angles - for example rendering box with bigger OutlineThickness can show that the black sides are rendered away from the actual 3D object.
When 3D scene has many 3D objects, then using the technique can affect performance because the scene needs to be rendered 2 times (once for black background and once for standard rendering). This technique works with multi-sampling and super-sampling.";

But instead of expanding the object's geometry, the scene is rendered normally with black color. Then an ExpandPostProcess is used to expand the rendered black scene for the specified amount.
This technique can produce more accurate results then using SolidColorEffect with OutlineThickness (especially for objects with sharp edges). But it is the slowest because it requires to render the scene again and then perform a two pass post-processing. This technique is not support when multi-sampling is used.";
EdgeDetectionPostProcessInfoControl.InfoText =
@"EdgeDetectionPostProcess is a 2D texture post process that uses Sobel edge detection algorithm to detect edges based on the changes of color in the rendered 3D scene - if colors are different enough then a black edge is added to the rendered image.
If the rendered scene has many 3D objects, then this algorithm is the fastest because it does not require to render the 3D scene again. This technique does not support multi-sampling and super-sampling (executed after back-buffer is resolved).";
