In Inkscape I'm creating a 3D cube like shape with some curvature along the border edges. To simulate the curvature I'm using two adjacent paths with linear gradients facing opposite direction, like a bilinear gradient.
But how do I merge this junction point seamlessly along the corner curve? Blurring the paths reduces the seam a bit, but also makes the paths bloom outside the boundary of the cube. Is it possible to create a gradient along a path?
