API Version: NVN API 5515 Exclusive Feature Name: NVN Expressive Motion Blur Target Hardware: Nintendo Switch (Tegra X1/X1+) 1. Overview Traditionally, Motion Blur on the Switch is handled via generic post-processing shaders that sample the velocity buffer. This method is computationally expensive (texture reads) and often prone to artifacts (ghosting) at lower resolutions.
leverages the low-level access granted by API version 5515 to bypass standard rasterization pipelines for specific geometry. It introduces a hardware-accelerated "Geometry Smear" technique, allowing developers to generate high-quality per-object motion blur with near-zero performance cost compared to traditional full-screen post-processing. 2. Technical Implementation This feature utilizes the nvnGenerateGeometrySmear command, a low-level GPU instruction exposed exclusively in the 5515 SDK. Instead of calculating blur in screen space, the GPU tessellates geometry along the motion vector in world space during the vertex shader stage.
void ApplyExpressiveMotionBlur(NVNcommandBuffer *cmdBuf, NVNdrawAction action) { // 1. Enable the exclusive 5515 "Smear" Polygon Mode // This tells the GPU to interpolate vertices between current and previous positions nvnCommandBufferPolygonMode(cmdBuf, NVN_POLYGON_MODE_SMEAR);
