Better Transparency with VTK and WebGPUTransparency is a seemingly simple and powerful visualization technique to facilitate the understanding of complex geometric structures. However, to do so accurately, and at highly interactive frame rates, is challenging. That is why we're excited about VTK's new WebGPU deep framebuffer. It collects translucent rendering fragments in one geometry pass, then composites them in depth order, preserving relationships that VTK's default OpenGL transparency averages away. For nested scans and intersecting simulation surfaces, this gives us a clearer way to explore how the pieces fit together.๐Kitware IncWelcome to SwedenCpp

A performance trap: when store forwarding failsA store does not go straight into the cache. Waiting for that write would stall the processor. It sits in a store buffer, and a later load can take its bytes from that buffer. That is store forwarding. Forwarding works when the load is the same size as the store, or smaller and completely inside โฆ Continue reading A performance trap: when store forwarding fails๐Daniel Lemire's blog

Who Owns This Memory?In my last blog, I said that to_numpy() gives you a view for some VTK arrays and a copy for others. That deserves a closer look.

Open source as a research methodMany people still picture innovation as a line. The professor thinks and publishes. The engineer reads the paper and designs a product. The customer consumes it. It rarely works that way. The industrial revolution was not set off by professors writing papers. It was driven by demand for cheap and better clothing for the masses. โฆ Continue reading Open source as a research method๐Daniel Lemire's blog

C++26: std::constant_wrapperThereโs a fundamental gap in C++ that trips up everyone who reaches for it: you canโt pass a constexpr value through a function boundary and have it remain constexpr on the other side. The value is known at compile time, the function is constexpr, but the parameter inside the function body is not a constant expression.
