Thanks that helps a lot. It looked like the previous example was built around generating individual images per event and then mashing them together. This one looks nice. Btw I'm not looking to average the accumulated events. At the end I will be normallizing based on the minimum and maximum values i...

Aaah, that sounds promising. the missing bit that I still haven't got a solid lead on is how to additively render them into a float texture so that their weights accumulate(additive blending). I think the steps after this are pretty easy.

snibgo Does that breakdown suggest that every event would need to be rasterized into the right 'world space' on a giant image and then a 2nd stop to mash that huge set of indivisual images together ? I don't need a mean of the images, I need the values additively blended together For instance, my 'w...

Can you point me in the right direction for generating an additive floating point image with radial gradients ? Thanks for your time. As an aside. Perhaps this is not doable, but are there any mechanisms to visualize 3d event sets? One down side to doing a 2d heightmap is the blending and loss of th...

I assume you mean a grey scale with a floating point color value or 32 bit 1 channel image or something. The first part ought to be as simple as rendering radial gradients into an image with additive blending. The additive pixel values will accumulate arbitrarily for all the events. Afterwards I jus...

I'm looking for ways to generate a 2d heatmap from a list of 'events' that provide a variable additive influence that should ultimately be normalized and mapped to a color range. There will be potentially tens of thousands of events that may result in arbitrarily large accumulations of influence acr...
