Check if a capture is currently loaded in RenderDoc. Returns the capture status and API type if loaded.

Get the list of all draw calls and actions in the current capture.

Args: include_children: Include child actions in the hierarchy (default: True) marker_filter: Only include actions under markers containing this string (partial match) exclude_markers: Exclude actions under markers containing these strings (list of partial matches) event_id_min: Only include actions with event_id >= this value event_id_max: Only include actions with event_id <= this value only_actions: If True, exclude marker actions (PushMarker/PopMarker/SetMarker) flags_filter: Only include actions with these flags (list of flag names, e.g. ["Drawcall", "Dispatch"])

Returns a hierarchical tree of actions including markers, draw calls, dispatches, and other GPU events.

Get a summary of the current capture frame.

Returns statistics about the frame including:

• API type (D3D11, D3D12, Vulkan, etc.)

• Total action count

• Statistics: draw calls, dispatches, clears, copies, presents, markers

• Top-level markers with event IDs and child counts

• Resource counts: textures, buffers

Find all draw calls using a shader with the given name (partial match).

Args: shader_name: Partial name to search for in shader names or entry points stage: Optional shader stage to search (if not specified, searches all stages)

Returns a list of matching draw calls with event IDs and match reasons.

Find all draw calls using a texture with the given name (partial match).

Args: texture_name: Partial name to search for in texture resource names

Returns a list of matching draw calls with event IDs and match reasons. Searches SRVs, UAVs, and render targets.

Find all draw calls using a specific resource ID (exact match).

Args: resource_id: Resource ID to search for (e.g. "ResourceId::12345" or "12345")

Returns a list of matching draw calls with event IDs and match reasons. Searches shaders, SRVs, UAVs, render targets, and depth targets.

Get detailed information about a specific draw call.

Args: event_id: The event ID of the draw call to inspect

Includes vertex/index counts, resource outputs, and other metadata.

Get GPU timing information for actions (draw calls, dispatches, etc.).

Args: event_ids: Optional list of specific event IDs to get timings for. If not specified, returns timings for all actions. marker_filter: Only include actions under markers containing this string (partial match). exclude_markers: Exclude actions under markers containing these strings.

Returns timing data including:

• available: Whether GPU timing counters are supported

• unit: Time unit (typically "seconds")

• timings: List of {event_id, name, duration_seconds, duration_ms}

• total_duration_ms: Sum of all durations

• count: Number of timing entries

Note: GPU timing counters may not be available on all hardware/drivers.

Get shader information for a specific stage at a given event.

Args: event_id: The event ID to inspect the shader at stage: The shader stage (vertex, hull, domain, geometry, pixel, compute)

Returns shader disassembly, constant buffer values, and resource bindings.

Read the contents of a buffer resource.

Args: resource_id: The resource ID of the buffer to read offset: Byte offset to start reading from (default: 0) length: Number of bytes to read, 0 for entire buffer (default: 0)

Returns buffer data as base64-encoded bytes along with metadata.

Get metadata about a texture resource.

Args: resource_id: The resource ID of the texture

Includes dimensions, format, mip levels, and other properties.

Read the pixel data of a texture resource.

Args: resource_id: The resource ID of the texture to read mip: Mip level to retrieve (default: 0) slice: Array slice or cube face index (default: 0) For cube maps: 0=X+, 1=X-, 2=Y+, 3=Y-, 4=Z+, 5=Z- sample: MSAA sample index (default: 0) depth_slice: For 3D textures only, extract a specific depth slice (default: None = full volume) When specified, returns only the 2D slice at that depth index

Returns texture pixel data as base64-encoded bytes along with metadata including dimensions at the requested mip level and format information.

Get the full graphics pipeline state at a specific event.

Args: event_id: The event ID to get pipeline state at

Returns detailed pipeline state including:

• Bound shaders with entry points for each stage

• Shader resources (SRVs): textures and buffers with dimensions, format, slot, name

• UAVs (RWTextures/RWBuffers): resource details with dimensions and format

• Samplers: addressing modes, filter settings, LOD parameters

• Constant buffers: slot, size, variable count

• Render targets and depth target

• Viewports and input assembly state

List all RenderDoc capture files (.rdc) in the specified directory.

Args: directory: The directory path to search for capture files

Returns a list of capture files with their metadata including:

• filename: The capture file name

• path: Full path to the file

• size_bytes: File size in bytes

• modified_time: Last modified timestamp (ISO format)

Open a RenderDoc capture file (.rdc).

Args: capture_path: Full path to the capture file to open

Returns success status and information about the opened capture. Note: This will close any currently open capture.
