URP Support

[unitycoder]

using Unity 2019.4.25f1 + URP 7.7.1

temporary fix for URP+WorldSpace Canvas issue (point cloud get "stuck" inside canvas)
You dont need to do this, if you don't have world space canvas.
This is only for V1 (.bin) and V2 (.ucpc) formats.

• Create script CustomRenderPassFeature.cs (copy below)
• Select UniversalRenderPipelineAsset_Renderer
• Click Add Renderer Feature/CustomRenderPassFeature *this wont be visible, if you didnt create the script first
• Modify PointCloudViewerDX11.cs, add this line to class variables (somewhere before Awake() line):
  public static PointCloudViewerDX11 instance;
  Modify Awake() to:

void Awake()
{
    instance = this;
    applicationStreamingAssetsPath = Application.streamingAssetsPath;
}

using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Rendering.Universal;

public class CustomRenderPassFeature : ScriptableRendererFeature
{
    class CustomRenderPass : ScriptableRenderPass
    {
        CommandBuffer commandBuffer;

        public override void Configure(CommandBuffer cmd, RenderTextureDescriptor cameraTextureDescriptor)
        {
            commandBuffer = new CommandBuffer { name = "PointCloudViewer" };
        }

        public override void Execute(ScriptableRenderContext context, ref RenderingData renderingData)
        {
            if (unitycodercom_PointCloudBinaryViewer.PointCloudViewerDX11.instance == null) return;
            commandBuffer.Clear();
            commandBuffer.DrawProcedural(Matrix4x4.identity, unitycodercom_PointCloudBinaryViewer.PointCloudViewerDX11.instance.cloudMaterial, 0, MeshTopology.Points, unitycodercom_PointCloudBinaryViewer.PointCloudViewerDX11.instance.points.Length);
            context.ExecuteCommandBuffer(commandBuffer);
        }

        public override void FrameCleanup(CommandBuffer cmd)
        {
        }
    }

    CustomRenderPass m_ScriptablePass;
    public override void Create()
    {
        m_ScriptablePass = new CustomRenderPass();
        m_ScriptablePass.renderPassEvent = RenderPassEvent.AfterRenderingOpaques;
    }

    public override void AddRenderPasses(ScriptableRenderer renderer, ref RenderingData renderingData)
    {
        renderer.EnqueuePass(m_ScriptablePass);
    }
}

Using Unity 2020.3.21f1 + URP 10.6.0 + V3 (.pcroot) viewer

• Create script CustomRenderPassFeature.cs (copy contents below)
• Select UniversalRenderPipelineAsset_Renderer
• Click Add Renderer Feature/CustomRenderPassFeature *this wont be visible, if you didn't create the script first
• Modify PointCloudViewerTilesDX11.cs, add these changes:

// BEFORE
PointCloudTile[] tiles;
// AFTER
internal PointCloudTile[] tiles;
// BEFORE
int tilesCount = 0;
// AFTER
internal int tilesCount = 0;
// BEFORE
        void Awake()
        {
            applicationStreamingAssetsPath = Application.streamingAssetsPath;
            FixMainThreadHelper();
        }
// AFTER
        public static PointCloudViewerTilesDX11 instance;
        void Awake()
        {
            instance = this;
            applicationStreamingAssetsPath = Application.streamingAssetsPath;
            FixMainThreadHelper();
        }
// BEFORE
public void OnRenderObject()
// AFTER
public void DisabledOnRenderObject()

CustomRenderPassFeature .cs:

using unitycodercom_PointCloudBinaryViewer;
using UnityEngine;
using UnityEngine.Rendering;
using UnityEngine.Rendering.Universal;

public class CustomRenderPassFeature : ScriptableRendererFeature
{
    class CustomRenderPass : ScriptableRenderPass
    {
        CommandBuffer commandBuffer;

        public override void Configure(CommandBuffer cmd, RenderTextureDescriptor cameraTextureDescriptor)
        {
            commandBuffer = new CommandBuffer { name = "PointCloudViewer" };
        }

        public override void Execute(ScriptableRenderContext context, ref RenderingData renderingData)
        {
            if (PointCloudViewerTilesDX11.instance == null) return;

            commandBuffer.Clear();
            for (int i = 0, len = PointCloudViewerTilesDX11.instance.tilesCount; i < len; i++)
            {
                if (PointCloudViewerTilesDX11.instance.tiles[i].isReady == false || PointCloudViewerTilesDX11.instance.tiles[i].isLoading == true || PointCloudViewerTilesDX11.instance.tiles[i].visiblePoints == 0) continue;
                commandBuffer.DrawProcedural(Matrix4x4.identity, PointCloudViewerTilesDX11.instance.tiles[i].material, 0, MeshTopology.Points, PointCloudViewerTilesDX11.instance.tiles[i].visiblePoints);
            }
            context.ExecuteCommandBuffer(commandBuffer);
        }

        public override void FrameCleanup(CommandBuffer cmd)
        {
        }
    }

    CustomRenderPass m_ScriptablePass;
    public override void Create()
    {
        m_ScriptablePass = new CustomRenderPass();
        m_ScriptablePass.renderPassEvent = RenderPassEvent.AfterRenderingOpaques;
    }

    public override void AddRenderPasses(ScriptableRenderer renderer, ref RenderingData renderingData)
    {
        renderer.EnqueuePass(m_ScriptablePass);
    }
}

Unable to test due to using PointCloudViewerTilesDX11.CS instead of non-tiled version. Question though regarding the CustomRenderPassFeature Script.

Where do you load the data into the command buffer for it to "commandBuffer.DrawProcedural(); I dont see anywhere for the data to be loaded, let alone to be drawn.

[unitycoder]

ah ok, ill need to check on the tiles viewer. (le me know your unity/urp version also)
that custompass feature, it uses data from my viewer, so its already loaded (and assigned to that cloudmaterial)
and commandBuffer.DrawProcedural() is the method to actually draw.

[Rickmc3280]

Interesting. So the data is stored in the material? Since I do a lot procedurally, it always revolves around uploading it to Mesh.Vertices, Mesh.Colors etc. Guess it is a different way of thinking

URP 12.1.1/ Unity 2021.2.XX

[unitycoder]

ok then that script above might not work, ill check with that version.

[unitycoder]

Now first message contains steps for V3 format also. @Rickmc3280
