I rapidly outstripped my Gimp/inkscape knowledge on this one. I know this needs to have a gradient to adequately light all the way to the top. What I don’t know is the optimal way to get there. Obviously deeper at the top is the goal.
However, what is the best approach? The figures represent my cousin and his wife, they are avid Cosplay participants. So I combined their two passions.
Would it be possible to engrave the image as it is? with the 3d engrave function? I would be ok with filled outlines for the images.
You’re not going to get a range of shades that give you enough contrast to provide much detail. 3D Engrave is good for carving shapes into a surface, but not for photo-like detail.
If you have plenty of material and want to try, just go for it and experiment. You’d probably have better results with Covert to Dots, but I’ve not seen good results with photo-like lit acrylic. It’s better suited to solid shapes or wire-frame. A cartoon-like outline drawing would be more appropriate (and then Vary Power would be fine.)
If you want to change the intensity of an image across a range (gradient), you can simply build the gradient on a second layer, and “multiply” with your original image, merging/flattening to produce the output.
Another thing that can be a trap for edge-lit stuff is a narrow base that spreads out as it goes up… which unfortunately describes your heart shape. It might work ok, there are a lot of variables. I tested this out on a pizza shape once that was the extreme version of this, and it was a total fail.
Oh that is totally true. I am actually going to lop of the bottom of the heart shape so the LED feeds across the whole width of the array. The heart outline in the uploaded png was merely there for the placement.
I converted the two images to gradients, so hopefully my test run will make me smile
won’t be able to do it until much later. Daughter is in Talent show most of today.
I don’t do gradients, I’ll just divide the designs into sections graduated by increasing power as the design progresses upward from the light source. It only takes a small amount of power to get the depth for exposure.
It appears that the face is much clearer. I am kinda stuck on the face for the officer, as his fiancé doesn’t have a good picture of HIM in his uniform. so I had to use a “stock” photo of the same style uniform.
The wedding is next week, his father is VERY ill and won’t be out of the hospital for the event. So I’m working hard for something a bit special.
I just wanted to show you the final product! I sillt have to file off the little nub at the top where the clamp was in the way of the heart cut. That sucker DID NOT show up in the camera view. it is about 10 inches tall. I am pretty pleased as this matched my vision. usually my brain exceeds my ability to execute.
