Three.js Shadows Explained | Tutorial for Beginners! (JavaScript)


Follow me on: Patreon: 🤍 Twitter: 🤍 Instagram: 🤍 Github: 🤍 Three JS shadows are really easy to use and enable. In this project we'll explore the different shadow types available in three js, which lights support shadowmapping, and we'll step through the code in JavaScript to add them to a scene. We'll walk through setup at the WebGLRenderer level, choosing the type of shadowing that three js will use, before looking at individual lights, and other options like setting individual mesh instances to cast or receive shadows optionally. This is part in a series of tutorials on Three.js, aimed at helping beginners understand everything from the ground up. This is a beginners course, aimed at people with no background in the subject. We've covered simple setup and basic 3d worlds, and this project should give you a solid understanding of three.js shadow capabilities. The three.js library is available in JavaScript for cross-browser 3d graphics, wrapping webgl and making high level functionality available in the web browser. It’s an extremely mature and well maintained library that I use for many of these videos. In the video, we cover: * What is shadow mapping, how does it work from a conceptual point of view. * What lights in three js support shadows and which don't. * Mesh shadow configuration. * Breakdown of the shadow types, including BasicShadowMap, PCFShadowMap, PCFSoftShadowMap, and VSMShadowMap * Using castShadow and shadow camera on DirectionalLight, PointLight, SpotLight * How to instantiate and use each in JavaScript.

A Visual Explanation of Cascaded Shadowmaps


Apologies for the mic volume; didn't notice until it finished rendering :P The source code for the Cascade Solver: 🤍 My Vulkan renderer project: 🤍 The shadowmaps are not filtered. This is partly because I wanted to showcase the resolution changes at different distances, and the shimmering effect... it's also because I haven't finished that yet.

Filtered Reflective Shadow Maps


The usual RSM is first dithered using Cranley-Patterson rotation with a per-pixel dither mask (blue noise here), then filtered using edge-aware a-trous filter.

Shadowmap tutorial w/ Blender & Sollumz for GTA 5 / FiveM


Shadow map tutorial for GTA 5 / FiveM using Blender 3.3 Notes: !! Use Blender 3.3 !! (doesn't work on newer versions of Blender since the shadow render pass has been removed) - You can use "shrink/fatten" in edit mode instead of scaling down the geometry (depends on your geometry) - After the first bake, you can delete all of the unnecessary faces, unwrap again, and rebake to improve your texture - if you need shadows on surfaces (like the tennis table) just create a new plane on top of the surface in the shadowmap geometry, and unwrap it with the rest of the faces. - You can use UV packer free addon to unwrap, it gives good results sometimes : 🤍

Unreal Engine 5.1 - Virtual Shadow Map Performance Comparison (W/Nanite Foliage)

Rectilinear Texture Warping for Fast Adaptive Shadow Mapping


Conventional shadow mapping relies on uniform sampling for producing hard shadow in an efficient manner. This approach trades image quality in favor of efficiency. A number of approaches improve upon shadow mapping by combining multiple shadow maps or using complex data structures to produce shadow maps with multiple resolutions. By sacrificing some performance, these adaptive methods produce shadows that closely match ground truth. This paper introduces Rectilinear Texture Warping (RTW) for efficiently generating adaptive shadow maps. RTW images combine the advantages of conventional shadow mapping - a single shadow map, quick construction, and constant time pixel shadow tests, with the primary advantage of adaptive techniques - shadow map resolutions which more closely match those requested by output images. RTW images consist of a conventional texture paired with two 1-D warping maps that form a rectilinear grid defining the variation in sampling rate. The quality of shadows produced with RTW shadow maps of standard resolutions, i.e. 2,048×2,048 texture for 1080p output images, approaches that of raytraced results while low overhead permits rendering at hundreds of frames per second.

Shadow Mapping


The central point where the ceiling light source rays hit the floor is utilized, in order to map the cast shadows in the perspective drawing, beginning with the Simple Box Form drawing. These generalized shadow shapes are then carried over to the Detailed Line Drawing and are filled in with hatching and a 0.1 Pigment Liner.

Unreal Engine 5 - Optimizing Lumen, Lumen Reflections and Troubleshooting Virtual Shadow Maps


HI! Here I want to share with you what I found out the last several days testing UE5. I came across exciting optimizations (at least to me) and advanced settings for lumen, lumen reflections and virtual shadow maps, which help troubleshooting issues or weaknesses I experienced so far, and can even improve the overall quality of these features. I apologize for my poor english skills (and also deeply for the clipping sometimes, it really hurts my soul, but I just wanted to put this out so it is available as soon as possible). I hope you are still able to understand everything I want to share and at least find it helpful for your needs of experimentation. If anything might not be clear to you, I will gladly try to answer your questions in the comments, as far as I know/understand this stuff myself. Please note again: I am NOT a professional tutor or Unreal Developer! I do not even make tutorials in general. Everything I explain in this video is based on experimentation, combined with assumptions made of only some background knowledge about the whole lighting topic. Added console commands to one user's suggestion: Virtual Shadow Maps: r.Shadow.Virtual.ContactShadowLength - controls precision of contactShadows to the casting object. Set it to 0.01 for example, or lower. r.Shadow.Virtual.ResolutionLodBias - controls smoothing of virtualShadows based on distance. Be careful to select the right option according to your light-type. 0 or negative values for wider smoothing range. r.Shadow.Virtual.NormalBias - use this to fix virtual shadow artifacts which appear when the casting shadow is to close to casting object's surface. Set it to 1 or even higher values like 1.5. Default should be 0.5. Lumen Reflections: r.Lumen.Reflections.HierachicalScreenTraces.MaxIterations - reduce this to low values to get rid of unrealistic dark areas (shadows?) in lumen reflections. Set it to 4 for example. r.Lumen.DiffuseIndirect.MaxMeshSDFTraceDistance - seems to control the distance to which distance field meshes are taken into account, affecting basically the mesh clarity/resolution range in lumen reflections. Lumen Global Illumination: r.Lumen.DiffuseIndirect.MinTraceDistance - increase this if you find nearby areas from light reflecting surfaces to be to dark (very subtle). r.Lumen.ScreenProbeGather.MaxRayIntensity - values between 0 and 1. Controls the overall amount of indirect lighting intensity in the whole scene. r.Lumen.ScreenProbeGather.FullResolutionJitterWidth - higher values mean less jittering (it gets wider) but more visible noise from the indirect lighting. 1 should be default. r.Lumen.ScreenProbeGather.DownsampleFactor - lower values mean more probes are used to collect light for the scene, which increases overall lighting precision/quality and reduces noise, but for a high cost in performance, default is 16 and should only be changed if absolutely necessary. r.Lumen.ScreenProbeGather.SpatialFilterMaxRadianceHitAngle - gives some control over ambient occlusion (in my opinion, but I don't really know, what it does). Higher values for sharper and (I find more precise looking) ambient occlusion. I suggest to think in degrees from 0 to 90. r.Lumen.ScreenProbeGather.SpatialFilterNumPasses - how good the jittering is filtered, higher values give smoother lighting results.

Reflective Shadow Maps [2022-2-24]


This week, Jaker will present the paper "Reflective Shadow Maps." This paper introduces an algorithm for interactive rendering of plausible indirect illumination. Paper Link: 🤍 Join our discord server: 🤍

Global illumination on view-adaptive imperfect shadow maps


This is my variation of imperfect shadow maps that uses compute shader tesselation approach as well as an advanced version of pull-push algorithm. All indirect lighting in this scene is done by ISM only, there's no ambient occlusion or ambient lighting term. Compute shader-based point tesselation is way more flexible than tesselation shader-based because it allows to produce unlimited numbers of point primitives per every triangle. My version of pull-push algorithm uses precise 3d arithmetics on ray-disk intersections instead of screenspace 2d ellipse approximations that allows to fill way larger holes with less artifacts. What's most important, depth and normals used by ISM are interpolated without numerical errors at all. Please turn annotations on for basic comments on shown debug info. The whole program is written on C and OpenGL 4.5 without any third-party wrappers.

Cascaded Shadow Mapping: Frustum Splits


For Cascaded Shadow Mapping, the view frustum needs to be split into several sub frustums. In this video, the splits are performed based on fixed distances from the viewer and each split is rendered in a different color. At about mid-point of the clip, the frustums for the shadow projections are shown. Check out code samples and corresponding blog entry on 🤍

Imperfect Shadow Maps


We present a method for interactive computation of indirect illumination in large and fully dynamic scenes based on approximate visibility queries. While the high-frequency nature of direct lighting requires accurate visibility, indirect illumination mostly consists of smooth gradations, which tend to mask errors due to incorrect visibility. We exploit this by approximating visibility for indirect illumination with imperfect shadow maps—low-resolution shadow maps rendered from a crude point-based representation of the scene. These are used in conjunction with a global illumination algorithm based on virtual point lights enabling indirect illumination of dynamic scenes at real-time frame rates. We demonstrate that imperfect shadow maps are a valid approximation to visibility, which makes the simulation of global illumination an order of magnitude faster than using accurate visibility.
