      Dual graphics cards is unsupported (meaning we are unable to provide tech support) since we have no way to create the same/similar setup.

      With that said you can use more than one card. 
      What is important is that you don't share/mix video from one output path to another.

      So if you:

       add a movie player, and connect its output to stage 1 (using gpu1)add a movie player, and connect its output to stage 2 (using gpu2)

      Don't try to mix the two videos together in any way.. keep them separate. Mixing will require moving the texture from one gpu to the other, and will be a spped/bottleneck.

      No Isadora allows you to move video in anyway you like, so its very flexible. If you can keep the video flow simple, and maintain individual paths, you can make it work very well.

      TEST, TEST, TEST!

      Start simple, and build up.. test constantly

      Magnificent indeed!!! Perhaps they'll be reintroduced: there's quite a strong guerrilla rewilding movement here in the UK...

      I am recording this as an issue we need to investigate. Thank-you for the report.

      Can you send the patch either here (if you're comfortable) or in a support ticket (see the link in my signature) so we can take a look at it? In medical terms, it can be hard to diagnose a patient over the phone rather than through a physical exam.

      Here is a GLSL shader, that will unwarp a 'fisheye' (its not going to be perfect, since its not calibrated to any specific lens), but it should provide a decent result.

      /* Fisheye Correction - Fragment Shader For Isadora GLSL Shader actor */ // ISADORA_PLUGIN_NAME("Fisheye Correction") // ISADORA_PLUGIN_DESC("Corrects fisheye lens distortion from an input video stream to create a flatter, non-fisheye output.") // ISADORA_FLOAT_PARAM(strength, strn, 0.0, 200.0, 100.0, "Amount of fisheye correction. Higher values remove more barrel distortion.") uniform float strength; // ISADORA_FLOAT_PARAM(zoom, zoom, 50.0, 200.0, 115.0, "Zooms the corrected image to hide curved black edges.") uniform float zoom; // ISADORA_FLOAT_PARAM(horz_center, ctrx, -100.0, 100.0, 0.0, "Horizontal center of the lens correction.") uniform float horz_center; // ISADORA_FLOAT_PARAM(vert_center, ctry, -100.0, 100.0, 0.0, "Vertical center of the lens correction.") uniform float vert_center; // ISADORA_FLOAT_PARAM(edge_softness, edge, 0.0, 20.0, 2.0, "Softens the edge where the corrected image runs outside the source.") uniform float edge_softness; // Built-in Isadora uniforms uniform vec2 resolution; uniform sampler2D tex0; void main(void) { vec2 uv = gl_TexCoord[0].xy; // Move coordinates so that 0,0 is the image center. vec2 center = vec2(0.5) + vec2(horz_center, vert_center) / 200.0; vec2 p = uv - center; // Correct for non-square aspect ratio. float aspect = resolution.x / resolution.y; p.x *= aspect; // Zoom after correction. Higher zoom crops the outer edges. p /= zoom / 100.0; // Distance from lens center. float r = length(p); // Barrel/fisheye correction. // The shader samples farther outward as pixels move from the center, // which visually straightens fisheye-curved lines. float k = strength / 100.0; float corrected_r = r * (1.0 + k * r * r); vec2 corrected_p = p; if (r > 0.00001) { corrected_p = normalize(p) * corrected_r; } // Undo aspect correction and return to texture coordinates. corrected_p.x /= aspect; vec2 sample_uv = corrected_p + center; // Create a soft mask so out-of-range areas fade to black. float soft = edge_softness / 100.0; float mask_x = smoothstep(0.0, soft, sample_uv.x) * smoothstep(0.0, soft, 1.0 - sample_uv.x); float mask_y = smoothstep(0.0, soft, sample_uv.y) * smoothstep(0.0, soft, 1.0 - sample_uv.y); float mask = mask_x * mask_y; // Clamp sampling to avoid texture wrapping artifacts. sample_uv = clamp(sample_uv, vec2(0.0), vec2(1.0)); vec4 color = texture2D(tex0, sample_uv); gl_FragColor = vec4(color.rgb * mask, color.a); }

      Hello all,

      There have been a few questions in the past few months, so I just wanted to give a *very* quick and dirty explanation of how to connect Isadora to Rokoko Studio in order to get tracking data from the Rokoko Smartsuit Pro/Pro II and Smart Gloves.

      Setup Steps: 

      Download and install IsadoraIf you don't have an Isadora license and want to be able to save your work, purchase an Isadora LicenseNote: There are short-term and long-term options for licenses. Check the store for more details.Download and install Rokoko Studio from Rokoko's website.Note: This software is what collects the live data from the suit/glovesGet a Rokoko Plus subscription so that you can stream the data to Isadora from the Rokoko Studio Software.Get your suit/gloves connected to your WiFi and ensure they show up in Rokoko StudioNote: If you are having trouble, feel free to consult:Rokoko's Onboarding Essentials YouTube playlistRokoko's help articlesDownload the Rokoko Studio Live Watcher Add-On, unzip it, and follow the setup steps inside to connect Rokoko Studio to IsadoraNote: If you are having trouble, feel free to consult Rokoko's article on connecting Rokoko Studio to Isadora.
